A seat assembly includes a seat cushion frame, a seat back frame, a bracket, a pin actuator, a sensor, and an electronic control unit. The seat back frame is pivotally connected to the seat cushion frame about a pivot axis. The bracket is fixed to the seat cushion frame. The bracket includes a cam surface, and a distance between the cam surface and the pivot axis varies along the cam surface. The pin actuation includes a pin. The pin actuator is fixed to the seat back frame. The pin actuator is configured to move the pin from a disengaged position to an engaged position. The electronic control unit determines whether the sensor detects the front collision of the vehicle and controls the pin actuator to move the pin from the disengaged position to the engaged position.

An inertial lock assembly is disclosed. In various embodiments, the inertial lock assembly includes a tracking rod oriented with respect to a longitudinal axis, a housing slidably disposed about the tracking rod, the housing including an inner surface having a first portion extending from an apex to a first end spaced longitudinally from the apex, a first sliding member slidably disposed about the tracking rod and within the housing proximate the first portion of the inner surface and a first binding member slidably disposed about the tracking rod and within the housing, the first binding member positioned between the apex and the first sliding member.

A vehicular locking device includes a bore having first and second ends. A gas generating device is proximate the first end. A piston is movable along an interior of the bore. The vehicular locking device includes first and second plates. The second plate includes an aperture. Activation of the gas generating device accelerates the piston through the aperture and the second plate preventing displacement of the second plate.

Aspects of the disclosure relate to reducing the likelihood of injury to a passenger in a collision. In one example, a system for reducing the likelihood of a passenger submarining, may include a restraining device for restraining the passenger. A second restraining device for further restraining the passenger may also be included in the system. A locking mechanism may be configured to prevent a seat back from reclining when the second restraining device is not activated.

A seat lock device includes: a striker installed in a vehicle body; and a lock unit provided on a seat back tiltable in a seat front-rear direction and holding the seat back in a standing state by locking the striker. The striker includes a base bracket attached to the vehicle body and a U-shaped rod locked by the lock unit, the base bracket has two support portions which respectively support end portions of the rod with a space therebetween in the seat front-rear direction, and at least one of the support portions deforms when a load exceeding a predetermined load is input to the rod so as to permit movement of the end portion of the rod supported by the support portion with respect to the base bracket.

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.
