摘要： A vehicle seat includes a seat cushion assembly for supporting an occupant seated thereon and a seat back cushion assembly for supporting the back of an occupant seated on the seat cushion assembly. A first mounting assembly is constructed and arranged to mount the seat cushion assembly on a vehicle floor and a second mounting assembly is provided which is constructed and arranged to mount the seat back cushion assembly on the seat cushion assembly. An adjusting mechanism is operatively embodied in one of the first and second mounting assemblies and is constructed and arranged to enable the cushion assembly mounted by the one mounting assembly to be moved in opposite directions through a range of adjustable positions with respect to the assembly on which the one mounting assembly mounts the cushion assembly. The adjusting mechanism also includes a locking and releasing device. A vehicle crash sensing system is operatively connected with the adjusting mechanism and is constructed and arranged to provide control of the movement of the cushion assembly mounted by the one mounting assembly in response to the sensing of a crash condition which occurs while said locking device is in the releasing position.

摘要： The vehicle safety seat supports an occupant and includes structure interconnecting the seat and the vehicle. The interconnecting structure is adapted to constrain the seat, upon vehicle deceleration, to follow a trajectory with respect to the vehicle which substantially minimizes a cost function associated with occupant injury. In a preferred embodiment, the structure constrains the mass center and seat angle to follow trajectories which substantially minimize primarily forward motion of the occupant in the vehicle frame of reference.

摘要： An inertia sensitive hinge mechanism allows rotation of a first hinge member relative to a second hinge member about a pivot during normal use and prevents rotation about the pivot when predetermined deceleration forces are present. The inertia sensing latching assembly includes an inertial actuator operatively connected to and rotatable with respect to the second hinge member. The inertial actuator includes first and second cam surfaces and a wedging surface located therebetween. The inertial actuator has a center of gravity spaced from a center of rotation. A first positioning device connected to the first hinge member positions the inertial actuator by sliding engagement with the first cam surface as the first hinge member rotates in an opposite direction when the predetermined forces are not present. A second positioning device connected to the first hinge member positions the inertial actuator by sliding engagement with the second cam surface as the first hinge member further rotates in the opposite direction when the predetermined deceleration forces are not present. When the deceleration forces are present, the first hinge member initially rotates in the opposite direction, and the inertial actuator is positioned by the predetermined deceleration forces such that the wedging surface engages the second positioning device preventing further rotation of the first hinge member in the opposite direction.

摘要： A vehicle seat having a backrest part hingedly connected to the frame so as to break forwardly about the hinged connection from a normal substantially upright position includes a braking device for preventing forward movement of the backrest part about the hinged connection under forces equivalent to less than a predetermined maximum forward force applied to the top of the backrest part but to permit forward movement of the backrest part under greater forces against a reaction provided by the braking device. The backrest part is preferably so constructed that no significant force may be applied to it by the knees of a passenger in a seat immediately behind. For example it may have an aperture in the region which will be immediately in front of the knees of a passenger occupying a seat immediately behind. The aperture may be covered on the front and/or back of the backrest part by light surface element, capable of deformation, detachment or fracture under impact from the knees of a passenger to enable them to pass through the aperture without applying significant force to the backrest part.

摘要： A seat adjustment latch, selectable at two different force levels, is attached to a slide adjustable seat in a motor vehicle equipped with a seat belt assembly, an inflatable air bag, and a knee restraint. The seat adjustment latch is interlocked with the seat belt assembly of the seat such that when the seat belt is unfastened, the seat adjustment latch is set to release the vehicle seat in the event of a rapid deceleration or impact to the vehicle above a predetermined level of severity. When the seat belt is fastened, the seat latch is set in its firmest possible retention setting and operates such that the inertia and kinetic energy forces of the seat and the occupant seated thereon will not move the seat forward in response to a severe frontal collision. In a preferred embodiment, the seat adjustment latch includes a shearing element configured as a tubular bolt for retaining the slide adjustable vehicle seat to the seat rails. The tubular bolt is selectively reinforced at a shear region by a moveable insert piece, the movement of which is influenced mechanically by the fastened/unfastened condition of the seat belt. In an alternate embodiment, the movement of the insert piece is controlled electrically.

摘要： An inertia responsive latch mechanism for vehicle seats including an inertia latch member (22) pivotally mounted on a back frame member (18). The back frame member (18) is pivotally supported by the support frame (12). The inertia latch member (22) coacts in a first position with the support frame (12) for limiting forward pivoting movement of the back frame from an upright position only when the initial forward movement of the back frame (18) exceeds a predetermined acceleration. The assembly is characterized by the support frame including a lip (34) to automatically coact with the inertia latch member (22) in a second position in the forwardly folded position for automatically locking the back frame in the forwardly folded position. A lever (36) is included to remove the inertia latch element from the second coacting position to allow the back frame member (18)to return to the upright seating position.

摘要： A seatback latching mechanism for use in a vehicle seat assembly having a backrest member pivotally tiltable over a seat member. The mechanism has a first latch means fixed relative to the seat member and a second latch means pivotally mounted on the backrest member for pivotal movement thereof between an unlatched and a latched position in which tilting movement of the backrest member over the seat member is restrained. Pendulum means are pivotally mounted on the backrest member for pivotal movement independently of the pivotal movement of the second latch means between first and second pendulum limit positions at which limit positions the pendulum means impinges upon the second latch means.In the normal upright position of the backrest member, the pendulum means is gravity biased to the first limit position in which the composite center of gravity of the pendulum means and the second latch means is positioned eccentrically of the pivot axis thereby urging the second latch means towards the unlatched position. Upon the occurrence of a first vehicular deceleration force sufficient to overcome the gravity biasing of the pendulum means to the first limit position, the pendulum means pivotally moves to the second pendulum limit position thereby increasing the sensitivity of the mechanism to latching, such that, upon the attainment of a second greater vehicular deceleration force, the second latch means moves rapidly to the latched position thereof.

摘要： An improved motor vehicle seat back hinge mechanism which includes an inertial sensitive latching device which prevents forward rotation of the seat back in the event of sudden vehicle deceleration. The vehicle seat hinge mechanism according to this invention improves over prior art designs by providing a quadrant component which does not present objectionable rearward protrusions which interfere with rear seat occupants while entering and egressing from the rear seat area and, further, avoids the presentation of sharp projections which could cause tearing and wearing of interior trim fabrics. Further, the pendulum type inertial sensing mechanism of the design according to this invention avoids the use of loose parts which may give rise to noise and rattle problems associated with rolling weight type inertial sensing mechanisms.
