摘要:
A forward head position correction collar is provided which in combination includes a shoulder collar assembly, a chin mastoid piece for engaging and positioning the head of a wearer of the collar; and interconnecting means for interconnecting the chin piece to the collar assembly as to enable the chin piece to be manually and preferably incrementally adjustable with respect to the shoulder collar assembly in a Z-direction to thereby adjust the supported head of the wearer from the forward head position to an increasingly corrected position. The interconnecting means is further adapted for displacing the chin-mastoid piece in a vertical direction with respect to the shoulder collar assembly simultaneously with and proportional to the incremental adjustment of the chin-mastoid piece along the Z-axis. The proportional vertical displacement with respect to the z axis displacement for the chin-mastoid support piece is that yielded by a point moving at about a 5 to 25 degree slope with respect to the horizontal Z-axis. The correction collar may further include a lordosis correction assembly secured to the rear of the collar and engageable with the rear of the wearer for applying corrective forces to at least one or more of the cervical vertebrae of the wearer.

A vehicle seat for use in military vehicles provides increased protection for a helmeted or unhelmeted combatant soldier. The seat includes a seat portion having a layer of high impact energy absorbing material. A back support portion adjoined to the rear of the seat portion extends upwardly for supporting the rearward side of the seated soldier. The back portion has a lower section for supporting the thorax and lower back, and two overlying sections which are positionable for supporting and restraining rearward movement of the helmeted or unhelmeted head and the neck. The overlying sections are moveable toward and away from the soldier and together define a surface and contour which interacts with the seated soldier during rear end impact to maintain the pre-collision shape of the soldier's supported spinal curves, to aid in avoidance of whiplash and similar injuries. Swivelable side portions actuated by sensors flank the sides of the soldier for further protection.

An apparatus for preventing whiplash related injuries to a passenger in a vehicle. The apparatus includes a frame supported on a seat of the vehicle, and a head and neck restraint secured to the frame and located behind the cranium and cervical spine of a seated passenger. The restraint comprises one or more fluid pressurized bladders, the walls of which are a tough flexible skin. The walls define a supporting device that interfits with the posterior contour of the passenger's cranium and cervical spine. This substantially simultaneously decelerates the cranium and cervical spine during a vehicle collision to prevent whiplash-related injuries to the passenger.

A vehicle-installed supporting seat for a passenger is provided, which includes a seat back provided with an integral head-neck restraint comprising a cranium support portion and a cervical spine support portion. Each portion includes a layer of resilient material supported on an underlying inflexible support shell, which together act to effectively define a contour that interfits with the posterior contour of the passenger's cranium and cervical spine. This contour thus presents a first surface located behind the passenger's cranium for contacting the approximate center of mass of the cranium and supporting the approximate central posterior area of the passenger's cranium, and a second surface located below the first surface and defining a substantially convex smooth curve, the maximum protrusion point of which projects anteriorly relative to where the first surface contacts the center of mass of the passenger's cranium, the second surface thereby contacting and supporting the posterior portion of the passenger's cervical spine substantially simultaneously with the contact of the passenger's cranium with the first surface. The support shell is rearwardly displaceable upon being subjected to impressed forces generated from the passenger pressing against the restraint as a result of a rear end impact at the vehicle. A controllably deformable energy absorbing crush zone is disposed to the rear of the shell as to be compressed by the rearward displacement of the shell. The interfitting contour and thereby the inflexible shell, upon being displaced by the impressed forces toward the underlying crush zone, retain the shape of the contour, whereby the cervical and cranium support portions act to substantially simultaneously decelerate the cranium and cervical spine of the passenger during a vehicle rear end impact while the controlled deformation of the crush zone absorbs energy, to prevent whiplash-related injuries to the passenger.

A posture correction collar is provided to adjust forward translation of the head of a hypothetical wearer relative to the shoulders, when the body is viewed perpendicularly to a sagittal plane (i.e., from the side of the body). The collar comprises a first assembly having a support member that shaped and dimensioned to wrap around and engage at least a portion of the upper area of the body of the wearer when the collar is used. A second assembly is movable relative to the first assembly. The second assembly has a first adjustable mechanism to progressively and incrementally move relative to the first support assembly and a second adjustable mechanism to engage a portion of the head of the wearer. The first and second adjustable mechanism are used to correct the posture of the wearer, by promoting progressive and incremental movement of the head relative to the shoulders to achieve an anatomically desired condition. In a preferred embodiment, the collar comprises an adjustable lordosis displacement assembly that is operatively secured to the first support assembly. The adjustable lordosis assembly being used to apply a corrective force to the upper, middle or lower cervical spine to selectively restore the lordotic curvature of the cervical spine of the wearer to an anatomically desired position, thereby adjusting the translation of the head and the posture of the wearer.

A seat is provided having a layer of high impact energy absorbing material and a sacral well provided therethrough. The seat may form a bottom portion of a vehicle seat that may further include a back support portion extending upwardly for supporting the rearward side of a seated individual. The back support may include a lower section for supporting the thorax and lower back, and an upper section. There may be one or more overlying sections positionable for supporting and restraining rearward movement of an individual.
摘要:
Apparatus for preventing or limiting spinal injuries to a passenger seated in a forward facing position in a moving vehicle during vehicular impact or sudden deceleration. The apparatus includes a vehicle-installed supporting seat for the passenger, the seat having a support portion behind the seated passenger which includes a resilient surface in contact with the supported passenger. The resilient portion is supported on an underlying stiff support shell. A controllably deformable energy absorbing crush zone is disposed to the rear of the shell as to be compressed by rearward displacement of the passenger, whereby the support portion acts to decelerate the supported spine of the passenger during a vehicle rear end impact, while the controlled deformation of the crush zone absorbs energy, to prevent or limit spinal injuries to the passenger. The crush zone material is characterized in a rear end collision by exhibiting a total energy absorption of the kinetic energy gained by the impact accelerated passenger of at least 80%; and the coefficient of restitution for the crush zone material being in the range of 0.05 to 0.4.

Apparatus for preventing whiplash-related injuries to a passenger in a vehicle. The apparatus includes a frame supported on a seat of the vehicle and located behind the cranium and cervical spine of a passenger on the seat. A layer of resilient material is supported on the frame, and defines a supporting means located behind the cranium and cervical spine of the passenger which defines one or more contours that interfit with the posterior contour of the passenger's cranium and cervical spine. The apparatus thereby contacts and supports the posterior portion of the passenger's cervical spine substantially simultaneously with contact and support of the passenger's cranium, thereby substantially simultaneously decelerating the cranium and cervical spine during a vehicle collision to prevent whiplash-related injuries to the passenger.

A forward head position correction collar is provided having first assembly mounted around the shoulder and neck portions of a wearer. A second assembly is movably connected to the first assembly. The second assembly includes a pair of opposed first and second adjustment assemblies that are used to position first and second cheek engagement pieces on the face of the wearer. The first and second cheek engagement pieces are joined to one side of a chin-mastoid piece that can be adjusted relative to the wearer. Preferably, a lordosis correction fulcrum assembly is formed within the first assembly to selectively and incrementally engage the rear of the wearer to apply corrective forces against the cervical area of the neck.
