A vehicle seat comprising a seat member and a backrest, wherein a belt connection is attached to or integrated into the upper end of the backrest, a mechanical coupling device is provided for coupling the backrest to the assembly for adjustment of the inclination of the seat member in the event of a collision. A triggering threshold is defined wherein the backrest is decoupled from the assembly under normal operating conditions, and wherein in a collision, when the triggering threshold is exceeded, the backrest pivots forwards and is finally coupled via the mechanical coupling device to the assembly, so that further pivoting of the backrest forwards triggers the assembly and causes the front region of the seat member facing away from the backrest to pivot upwards about a transverse axis.

A vehicle seat for attaching to a vehicle structure of a vehicle has a seat part and a backrest. The vehicle seat is movable in the longitudinal direction of the vehicle in relation to the vehicle structure and adjustable into a resting or lying seat position. In the event of a collision, the vehicle seat with the seat part is or can be pivoted upwards along an axis extending parallel to the vehicle transverse direction, with a front region facing away from the back rest. The backrest, at least in the resting or lying position, is or can be connected to the vehicle structure of a tensile force transmission element.

An impact absorbing device for a vehicle seat includes: a first base member; a second base member; and an impact absorbing member. The first base member rotatably supports the second base member. The impact absorbing member includes: a first fixing portion fixed to the first base member; a second fixing portion fixed to the second base member; and a deformable portion. The deformable portion is provided between the first fixing portion and the second fixing portion, and is configured to be bent by the rotation of the second base member. A distance between the first fixing portion and the second fixing portion in an undeformed state of the deformable portion has a value intermediate in a range of variation of the distance that varies depending on the bending of the deformable portion.

Devices, systems, and methodologies for vehicle seats include selectively collapsible safety layers providing collapsible support to reduce impulse experienced by the seated passenger imparted by the vehicle seat, which can reduce the likelihood and/or extent of injury attributable to occurrences exceeding threshold momentum changes, such as transportation vehicle collisions.

An assembly includes a seat bottom including a panel pivotable from a first position to a second position. The assembly includes a track supported by the seat bottom. The assembly includes a spring in the track and urging the panel toward the second position. The assembly includes a pyrotechnic actuator maintaining the spring in compression and actuatable to release the spring.

A vehicle seating assembly including a seat cushion and a seat frame assembly with a carrier assembly and a displaceable platform coupled to the carrier assembly and selectively deployable from a design position to a fully deployed position in response to a sudden deceleration of the vehicle.

A headrest is supported by an upper lateral member and a lower lateral member of a seat frame. A headrest stay is inserted through each of guide slots, both of which are formed in both the upper lateral member and the lower lateral member, and an extension wire is hooked on a lower end of the headrest stay. In a rear-collision, a seat back is retreated by a force received from a seated passenger, and a tension of the tension wire is accordingly loosened, which causes the headrest to be tilted forward by an urging force of tilt springs.

A seat rail module for a vehicle seat, comprising two longitudinal adjustment rails (10) arranged parallel to each other for guiding the vehicle seat (1) and adjusting its position in longitudinal direction, deformation units (18) which can be fastened or are fastened to the longitudinal adjustment rails (10), and fastening members (25) for fastening the seat rail module to the floor of a vehicle body, wherein the vehicle seat (1) can be fastened to the longitudinal adjustment rails (10) and the deformation units (18) are configured for deforming deformation members (19) when the vehicle seat is displaced in a main direction of travel, in order to decelerate the vehicle seat in the event of a crash, characterized in that the fastening members (25) are configured to fasten the seat rail module to the floor of the vehicle body by means of locking, and in that the fastening members (25) are mechanically unlocked when the vehicle seat (1) is displaced in longitudinal direction in the direction opposite to the main direction of travel beyond a predetermined limit line (8).

Also in the rear area in which the vehicle seat assumes a seat position which is shifted relatively far backward, such as will be possible in the future for autonomous driving or as a relax position, precautions for occupant protection are provided to a sufficient extent, even if front occupant protection systems, in particular front airbags, are no longer effective in this area.

Described is a breakover mechanism for a passenger seat that includes a frame member with a rear portion attached to two opposing sides of a seat back of the passenger seat wherein the frame member is at least partially disposed under a seat pan of the passenger seat, at least one moving portion attached to a forward portion of the frame member, a carriage portion fixedly attached to the seat pan; and a single point mechanism attached to the carriage portion. Once a threshold loading condition occurs, the single point mechanism changes states to facilitate movement of the moving portion relative to the carriage portion.

A seat sliding structure for a vehicle includes: a pair of left and right slide rails that include upper rails, which are attached to a lower portion of a vehicle seat, and lower rails, which support the upper rails such that the upper rails can slide in a vehicle longitudinal direction; rail guiding members that are fixed to a floor panel, and that support the lower rails such that the lower rails can slide in the vehicle longitudinal direction between a driving position at a vehicle front side and a relaxation position at a vehicle rear side; and a locking mechanism that locks movement of the slide rails at the relaxation position, and that releases a locked state when a frontal collision of the vehicle is detected or predicted.
