摘要:
A vehicle safety seat system includes a seat, and a frame and support surface that are movable with respect to each other between rest and attenuated positions, wherein the frame and support surface are respectively a first and second distance apart. A biasing mechanism biases the frame and support surface to the rest position between blast and slam down phases. A damper coupled between the frame and support surface has blast and rebound recovery resistance settings. The blast resistance setting is set to a predetermined value based on a weight of a seat occupant. The damper, during the blast phase, resists motion between the frame and support surface toward the attenuated position based upon the blast resistance setting, and after the blast phase and prior to the slam down phase, resists motion between the frame and support surface toward the rest position based upon the rebound recovery resistance setting.

An operator backrest in combination with a materials handling vehicle is provided. The backrest may comprise a primary support pad and gripping structure located in at least one side portion of the primary support pad. The gripping structure may be substantially even with or extend above a surface of a portion of the primary support pad surrounding the gripping structure for engagement with an operator positioned on the materials handling vehicle.

A seat for a vehicle. The seat includes an occupant support defining a support surface for an occupant of the seat, and a mounting assembly coupled to the occupant support and rigidly mounted to the vehicle. The mounting assembly resists non-vertical movement and guides vertical movement of the occupant support relative to the mounting assembly. The seat also includes a shear member having a first hardness and a sacrificial member have a second hardness lower than the first hardness. The sacrificial member is sheared by the shear member in response to a generally downward force on the occupant support arising from inertia of the occupant in the presence of a rapid upward movement of the vehicle. Shearing the sacrificial member absorbs energy associated with the rapid upward movement of the vehicle and accommodates downward movement of the occupant support relative to the mounting assembly, reducing acceleration of the occupant.

Disclosed are work machine vehicles having an operator protective structure with a seat mounted in the operator protective structure. In disclosed embodiments, first and second adjustable armrest assemblies are mounted to a structure of the seat such that the first and second armrest assemblies can be adjusted in fore and aft directions relative to a seatback of the seat. Vehicle controls are integrated with the first and second adjustable armrest assemblies such that adjustment of the first and second adjustable armrest assemblies adjusts positions of the vehicle controls relative to an operator sitting on the seat. After adjustment, the vehicle controls and the operator sitting on the seat are maintained at constant relative positions with respect to each other even as the work machine vehicle moves over rough terrain and the seat moves up and down. A nested seatbar is pivotably mounted to a structure of the work machine vehicle such that the nested seatbar can be moved to a down position in which portions of the nested seatbar are located between the first and second adjustable armrests.

A prisoner seat security device includes a retractable strap which hooks or clasps onto a prisoner, preferably by a restraint device on the prisoner, such as hand-cuffs. As the prison seats in the seat, the strap retracts. The officer can then lock the retraction mechanism so that the strap will not extend and the prisoner is held in place. When it is desired for the prisoner to get out of the chair, the lock is released, allowing the prisoner to stand the strap to be disconnected.

A vehicle provides upstanding and tilted (standstill for allowing a user to get on an off the vehicle) positions without movement of the vehicle. In the vehicle, even if the vehicle body tilts, a riding section is moved in the forward-backward direction to bring the vehicle to an orientation where the center of gravity (P) of the vehicle body is on a vertical line (V) passing through ground contact points (S1) or drive wheels (12). This controls the tilt angle of the vehicle body and the position of the riding section (13) so that the center of gravity (P) does not move. Thus, the upright position and the tilted position of the vehicle are achieved without movement of the vehicle (without rotation of the wheels). Further, influences such as an error in parameters and disturbance are compensated for by a balancer that moves in the forward-backward direction.

A safety seat for vehicles, including a seat portion having a rear end supported against vertical support straps of a strap framework secured to a vehicle. Each of two supports laterally disposed on the seat portion as a first end secured to the set. From the first end, each support extends in an inclined path, below the seat portion, to the vertical support straps. Each support has a free end remote from the first end and suspended in a loop formed on the vertical support straps. To tensioning straps are disposed beneath the seat portion and extend along side edges thereof from a front securement and the seat portion to a connection with the vertical support straps. Each tensioning strap has a length less than the distance between the front securement and the rear end of the seat portion.

A swiveling seat comprises a seat bottom, a swivel mechanism and a swivel resistance system. The swivel mechanism allows the seat bottom to rotate at least partially around a first axis of rotation. The swivel resistance system may include a first member that rotates with the swivel mechanism, a second member that is fixedly positioned relative to the swiveling of the swivel mechanism and an operator adjustable resistance control that is operated by the vehicle operator to bias the second member into the first member so as to vary the resistance required to swivel the operator's seat.
