A system (100) and method (900) for assessing for protecting the occupant (70) of a vehicle (50) during a rear crash (62). The system (100) can use a wide variety of assemblies, subassembly, and component configurations to protect the occupant (70) from undesirable kinematics (91). Such a system (100) can among other components include an anti-ramping guide (272) and/or a rear pretensioner (305).

A knee bolster assembly for a vehicle seat includes a knee bolster moveably mounted in proximity to the vehicle seat, the knee bolster selectively moveable between a first position, wherein a passenger is able to enter and exit the vehicle seat, and a second position, wherein the knee bolster is positioned directly in front of a seating surface of the vehicle seat, such that legs of a passenger seated within the vehicle seat are positioned between the seating surface of the vehicle seat and the knee bolster, the knee bolster adapted to prevent an occupant of the vehicle seat from sliding forward off the vehicle seat and restrict any hyper-extending of their lower legs due to forward inertia, and an energy absorbing device adapted to absorb energy when knees or legs of a passenger within the vehicle seat impact the knee bolster.

A passive safety system is provided for a vehicle. The passive safety system includes a support frame configured to be secured on the vehicle in a fixed position and a support surface configured to support a payload carried by the vehicle. The support surface is configured to float with respect to the support frame. The passive safety system includes an energy conversion device between the support frame and the support surface, and includes a frictional surface configured to engage a portion of the support surface when the support surface tends to move in a predetermined direction with respect to the support frame to thereby convert kinetic energy of the support surface into frictional energy and increase the stopping/braking distance.

A seat bottom assembly including a seat bottom frame having a front side and a back side, a seat plate having a front side and a back side, webbing stitches, and tear away stitches. The back side of the seat plate is coupled to the back side of the seat bottom frame. The webbing straps are coupled to and extending between the front side of the seat bottom frame and the front side of the seat plate, and tear away stitches connect two points of the webbing straps along a longitudinal axis so that the webbing straps are partially looped at locations of the respective tear away stitches. The tear away stitches separate and increase a length of the webbing straps in response to experiencing a threshold load in a direction perpendicular to the seat plate.

Provided is a conveyance seat that effectively reduces a load to be applied to an occupant at the time of a vehicle collision. A conveyance seat includes a seat back and a headrest. The seat back includes a chest support member inside the seat back, which receives a chest of an occupant to support the chest of the occupant when a backward movement load is applied to the occupant because of a vehicle collision. The headrest includes a head support member inside the headrest, which receives a head of the occupant to support the head of the occupant when the backward movement load is applied to the occupant. When the backward movement load is applied to the occupant, both the chest support member and the head support member receive the backward movement load.

A seat rail module with two rails for longitudinal adjustment of a vehicle seat comprises a drive member, at least one deformation member coupled to an associated rail for longitudinal adjustment, at least one fastening member for fastening the drive member, and an actuator for locking and unlocking the at least one fastening member. The deformation member is deformed upon displacement of the vehicle seat in a main direction of travel to dissipate crash energy and decelerate the vehicle seat. In a locked position of the fastening member, the drive member is directly secured to a rail by the fastening member. The fastening member is mechanically unlocked upon displacement of the vehicle seat beyond a predetermined limit setting, so that the drive member is coupled to an associated rail via the deformation member, to enable a displacement of an upper rail relative to a lower rail for dissipating impact energy.

Embodiments relate to dynamic stroking seats for vertical take-off and landing (VTOL) aircraft. Seat ballast tanks are attached to aircraft seats. The seats are sprung by a fixed or variable load energy absorption system. The weight of a user is determined and assigned to a corresponding seat of the user. Based on the weight of the user, the fluid level in the ballast tank is monitored and adjusted to achieve a target weight range.

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.
