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.

In one embodiment there is disclosed an energy attenuating vehicle seat. The seat includes a seat back pivotally connected to a seat pan, the seat back and the seat pan independently pivotal. At the pivot between the seat back and the seat pan there is a rotary energy attenuation device. The device extends between the seat back longitudinal members and the seat pan longitudinal members and is pivotally attached to the seat pan and the seat back allowing individual adjustment of the back or pan. The rotary energy attenuating device cooperates with a track system along the length of seat longitudinal members allowing for different directions of travel and height adjustment. The vehicle seat offers passive or active protection from impact and sudden acceleration (G force and Pressure Wave) due to accident or explosive events and is capable of automatically resetting.

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.

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.

An apparatus for dynamically stiffening a vehicle seat back may include a vehicle seat including a seat bottom mountable within a vehicle, a seat back extending upwardly away from the seat bottom, and a bight defined at a forward-facing interface between the seat bottom and the seat back, an occupant restraint harness coupled to the vehicle seat and engaging a top end of the seat back, and a seat back stiffening apparatus having a seat back stiffening member and an actuator coupled to the occupant restraint harness adjacent to or near the bight of the vehicle seat. The actuator may be responsive to a first force applied thereto by the occupant restraint harness in excess of a first threshold force to deploy the seat back stiffening member to couple to and between the seat bottom and the seat back to add stiffness to the seat back frame.

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.

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.
