A seat includes a seat-bottom frame, a seat-back frame rotatable relative to the seat-bottom frame between a forward position and a rearward position, and a first wedge and a second wedge on opposite side of the seat-back frame. The first wedge extends from the seat-back frame in the forward position to the seat-bottom frame, and the second wedge extends from the seat-back frame in the rearward position to the seat-bottom frame.

A vehicle seat includes a pressure-receiving member disposed rearwardly of an occupant between left and right side frames, and a rocking mechanism configured to cause a left side or a right side of the pressure-receiving member to move frontward and rearward. The rocking mechanism includes a first link member provided pivotally, a second link member provided pivotally on the first link member and pivotally connected to the pressure-receiving member, and an actuator configured to cause the first link member and the second link member to pivot.

The disclosure provides for a system that includes a seat mounted in a vehicle. The seat includes a base, a back support, a hinge, and a seat belt integrated into the seat. The back support is capable of rotating relative to the base and thereby reclining. The hinge is between the base and the back support and is configured to lock the back support in positions in relation to the base. The seat belt has a shoulder portion and a lap portion and is attached to the seat at a shoulder anchor in the back support and a base anchor in the base. When a generated torque, created from a forward force applied by the shoulder portion of the seat belt, exceeds a threshold amount of torque, the hinge is configured to unlock and back support is configured to rotate forward from a reclined position towards an upright position.

A vehicle seat console has at least one vehicle-mounted guiding element, at least one seat-mounted guiding element that runs parallel to the vehicle-mounted guiding element, and a longitudinal adjustment mechanism on which a driving device acts via a transmission mechanism and which is designed to cause a relative adjustment between the vehicle-mounted guiding element and the seat-mounted guiding element. The vehicle seat console is characterized in that the longitudinal adjustment mechanism and/or the transmission mechanism is/are equipped with at least one energy absorption device which is configured to dampen abrupt relative movements between the vehicle-mounted guiding element and the seat-mounted guiding element.

An airplane seat device having at least one backrest, at least one seat component coupled to the backrest and a backrest impact safety device which, by partially decoupling the backrest from the seat component, is provided to at least partly reduce impact forces on the backrest at least in the event of crash. The backrest impact safety device is provided to decouple the backrest from the seat component before the impact forces takes effect.

The present disclosure provides a vehicle collision mitigation apparatus and method, in which it is determined whether or not a collision will occur between a target vehicle and a lateral side of a host vehicle based on the paths of the host vehicle and the target vehicle, and if a collision is unavoidable, a traveling state, including a vehicle speed, steering, a suspension, or a position of a seat, is changed such that the impact caused by the collision is reduced. According to the present disclosure, it is possible to minimize damage due to the collision of the target vehicle with the lateral side of the host vehicle.

A device for constraining rotational motion of an actuator such as a seat actuator during a dynamic event. The device includes a first part attachable to a fixed frame member and carrying a first clip, and a second part attachable to an actuator and carrying a second clip. Prior to and following a dynamic event sufficient to cause actuator rotational motion the first clip and the second clip are disengaged. During the dynamic event the second clip is configured to engage the first clip to momentarily stop rotational motion of the actuator such that load on the actuator passes through the actuator shaft into the frame. In embodiments, the device is configured to minimize actuator deformation during a dynamic event while allowing a full range of standard motion during normal use of the actuator.

A method for adjusting a position of a vehicle seat from a reclined position to a pre-determinable safety position. The method includes detecting an imminent or ongoing frontal or semi-frontal collision, pretensioning a seat belt associated with the vehicle seat, the seat belt being directly or indirectly attached to a backrest of the vehicle seat, and adjusting the position of the vehicle seat from the reclined position to the pre-determinable safety position by means of a seat adjustment means associated with the vehicle seat, the seat adjustment means being actuated by a collision force generated by the imminent or ongoing frontal or semi-frontal collision and applied via a seat occupant and/or the seat belt to the vehicle seat. The present invention also relates to an occupant safety arrangement for a vehicle seat.

There is provided a seat break over device. The seat break over device features linkage members that connect the seat back to the quadrant arm. In the static condition, the linkage member acts as a rigid member, constraining rotation of the seat back relative to the quadrant arm. Upon impact of a certain inertial force, the linkage member interacts with a weighted member. The weighted member may include a suspended weight or mass that pivots about a horizontal axis. During a gravity load of a certain amount (e.g., a 16 g event), inertial loads act on the weighted member/hammer, which transfers a force onto the linkage member. This force moves the linkage member into an unstable mode, allowing forward rotation of the seat back with respect to the quadrant arm.

In severe traffic accidents, crumpling the front of the car causes the passenger's leg get stuck between the seat and the car's dashboard. In this article, the condition of the seat and occupant safety sack is checked, which keeps the passenger in place, in heavy crashes, then raises the occupant's knee, and pulls the front seats back as far as possible.
