An arrangement in passenger vehicles, that diverts the impact energy in lateral or side impacts away from the passengers to the remaining mass of the vehicle thereby protecting the passengers, and in the same arrangement provides utilitarian access to the vehicle, such utilitarian access making it possible to both install multi-element contoured surround seats for passengers and the driver, and also a safety device for head-on collision protection that obviates the need for conventional seat belts and front impact airbags. An indo-skeletal structural arrangement proposed for the vehicle, provides further benefits by targeting the strength of the vehicle to protect passengers while minimizing other massive elements in the vehicle. Side impact protection for the head and neck are proposed with airbags and aircushions.

A vehicle seat assembly is provided with a seat back frame. A bracket is provided with a substrate welded to the seat back frame. Two pairs of sidewalls extend from the substrate and are tapered with an enlarged region at an upper distal end. A pair of support plates are each supported by one of the two pairs of sidewalls and spaced apart from the substrate to provide a mounting surface. A pair of spaced apart tubes are each welded to the bracket mounting surface of one of the pair of support plates. A pair of head restraint posts are each received in one of the pair of tubes. A head restraint is supported upon the pair of head restraint posts, so that upon a rear vehicle impact, the bracket deforms as the pair of head restraint posts are translated toward the seat back frame.

A vehicle seat assembly is provided with a seat back frame with an upper crossbar. A deformable member is welded to the seat back frame. A pair of tubes is welded to the deformable member. A pair of head restraint posts are each received in one of the pair of tubes to support a head restraint. A pair of spaced apart limit bracket bases is welded to the upper crossbar and extend away from the seat back frame to support a pair of limit bracket contact portions. A pair of contact target plates are each welded to one of the pair of tubes, spaced apart from and aligned with one of the pair of limit bracket contact portions so that the deformable member deforms under a rear vehicle impact until the contact target plates contact the contact portions of the limit brackets.

A headrest position adjusting device for a vehicle, may include a first motor mounted to a seatback frame; a first link connected to the first motor to be rotatable to a predetermined first angle in a leftward-rightward direction; a second motor mounted to the first link; a second link connected to the second motor to be rotatable to a predetermined angle in an upward-downward direction; a third motor mounted to the second link; a third link connected to the third motor to be rotatable with respect to a rotation axis of the third motor; and a headrest frame connected to the third link and mounted in a headrest pad.

A rear-center head restraint system of an automobile vehicle includes a rear seatback of the automobile vehicle. A head restraint assembly is rotatably mounted to the rear seatback and is moved between a stowed position and an in-use position. The head restraint assembly includes a rear head restraint body defining an L-shape and includes a forward-facing surface moved toward a head of an occupant at the in-use position. At least a first link and a second link are rotatably connected to the seatback. The first link and the second link are also rotatably connected to the rear head restraint body. A release system rotates the head restraint assembly selectively between the stowed position and the in-use position.

A seating assembly for a vehicle comprises: a seatback; an airbag having a stowed position and an inflated position, the airbag being configured to inflate from the stowed position to the inflated position in response to the vehicle impacting an object; a head restraint coupled to the seatback, the head restraint including a forward position, a rearward position, and a locking mechanism preventing the head restraint from moving from the forward position to the rearward position after taking the forward position; and as the airbag inflates from the stowed position to the inflated position, the airbag forces the head restraint from the rearward position to the forward position. As the airbag inflates from the stowed position to the inflated position and forces the head restraint to the forward position, the airbag does not contact the one or more support bars and does not force the seatback to change position.

A seat device, particularly aircraft seat device, includes at least one head-support module, which device has a central cushion unit and at least one lateral cushion unit, wherein the lateral cushion unit is supported movably relative to the central cushion unit.
