A device for selectively monitoring and reducing a backward displacement of a vehicle seat in the event of an accident, having at least one stop element (4) which arranged on a pair (1) of seat rails and has a stop face (5) which is inclined with respect to a longitudinal axis of the pair (1) of seat rails, and having at least one stop body (6) which is arranged on the vehicle seat, having a contact face (8) which is arranged in a normal position at a distance from the stop face. In order to make available a device which efficiently reduces a backward displacement movement of a motor vehicle seat in a simple way in the event of an accident of the motor vehicle, there is provision that the stop element (4) and the stop body (6) are embodied and arranged with respect to one another in the mounted state in such a way that in a crash position which occurs in a tail-end impact with a motor vehicle having the vehicle seat, the stop face (5) of the stop element (4) and the contact face (8) of the stop body (6) enter into contact and as a result the backward displacement of the vehicle seat which is caused by the accident is reduced.

A plurality of elastic support members extends across a seat back frame that forms a skeleton of a seat back of the vehicle seat. A seat pad is disposed on the front sides of the elastic support members. An airbag is disposed between the elastic support members and a back portion of a covering in a deflated state. After having deployed, the airbag has such a shape that a deployment amount, in a front-back direction, of the airbag near a side of the seat back is greater than that near a center of the seat back. In a collision or the like, the airbag deploys in the seat back in such a way that, after having deployed, the airbag elastically supports an upper body of an occupant and elastically receives an impact force applied to a back surface of the seat back.

Disclosed is a car seat for protecting vertebral column, comprising: a backrest and a seat, wherein there is disposed with a troughed recess at a central portion of each of the backrest and the seat, so that when the backrest and the seat are subject to external impact, the impact damage incurred by the backrest and the seat onto a human vertebral column may be avoided, and in this way the human vertebral column can therefore be protected; in an embodiment of the present invention, there further comprises a plurality of viscous elastomers disposed inside the backrest and the seat, these viscous elastomers are set up in a corresponding arrangement on two sides of a human vertebral column, so as to assist in biasing the muscle on the two sides of the vertebral column to cause less direct impact by the external force, and to provide a cushioning effect.

A seat for a vehicle includes a frame. The frame includes a headrest portion. The seat for a vehicle also includes an energy absorption spacer coupled to the frame; a seat garnish positioned over the energy absorption spacer and the frame; and a seat trim cover. The seat trim cover has a first portion and a second portion. The first portion of the seat trim cover is coupled to the headrest portion, and the second portion of the seat trim cover extends between the energy absorption spacer and the seat garnish.

Proposed is a latch assembly with reduced rattling noise. The latch assembly includes a latch bracket mounted on a seatback frame, and includes a latch having a rear side portion hinge-coupled to the latch bracket, having a front side portion bent downward, and having an end portion provided with a claw portion. Furthermore, the latch assembly includes a cable connected to an upper surface of the latch, a pushing bar positioned below the rear side portion of the latch, a pressing bar horizontally positioned below the claw portion, and a link frame connecting the pushing bar and the pressing bar to each other, the link frame being connected to the latch bracket, and the link frame being configured such that the pressing bar is moved upward when the pushing bar is pressed downward by the latch.

A protection module for limiting and/or blocking a movement between at least two structural parts and/or a seat function of a vehicle seat in the event of a crash or during normal use may have one control unit, one protection unit and one coupling element arranged between the control unit and the protection unit. The coupling element may be formed to be variable in its length and couples the control unit and the protection unit to one another in such a way that a movement of the control unit can be transmitted to the protection unit. An adjustable vehicle seat may use the protection module.
