A collision protection system for a vehicle, the collision protection system including a seat having a seat back and at least one lateral support coupled to the seat back, where the at least one lateral support deploys based on one or more collision policies. The collision protection system further includes a side airbag, where the side airbag deploys based on the one or more collision policies, and where the at least one lateral support deploys between the seat and the side airbag to protect a user occupying the seat during a collision.

Side impact protection assembly for a vehicle

A seat belt anchorage assembly adapted to be coupled to an interior structure (e.g., a seat) of a vehicle, including: a seat belt attachment point adapted to receive one of a seat belt retention assembly and a seat belt buckle assembly; a translation mechanism coupled to the seat belt attachment point and adapted to translate the seat belt attachment point one or more of forwards and downwards with respect to the interior structure (e.g., the seat) of the vehicle responsive to a seat back of the vehicle being reclined. Optionally, the translation mechanism includes a mechanical linkage coupled between the seat back and the seat belt attachment point. Alternatively, the translation mechanism includes an electronic actuator coupled between the seat back and the seat belt attachment point.

Vehicle seat belt anchorage location dependent on seat back recline angle

A seat belt is wound around a spool and a spring biases the spool to rotate in a belt retraction direction. A sensor detects a retraction speed of the belt when the spool rotates in the belt retraction direction and generating a belt speed signal. An electrical drive unit receives the belt speed signal and applies a torque to the spool in a belt extension direction (opposite to the belt retraction direction) if the retraction speed exceeds a threshold value. The torque is of a magnitude sufficient to maintain the retraction speed below the threshold value. The electric motor and/or electrical control unit may be part of or otherwise integrated with a safety belt pre-tensioning system.

Method and system for seat belt retraction speed control

An occupant restraint system for a vehicle seat has a belt with a shoulder-belt portion extending diagonally across the seat between an upper portion of first side of the seat and a lower portion of a second side of the seat. An upper belt guide is mounted adjacent to the upper first side of the seat and engages the shoulder-belt to allow it to slide along the guide during belt retraction and extension. A safety sensor/control system generates a signal indicating a condition requiring improved occupant restraint in the seat. A guide actuator is activated in response to the safety sensor/control system signal and displaces the upper belt guide in a transverse direction relative to the seat. The displacement of the guide moves the shoulder-belt portion closer to the neck and/or shoulder of the seat occupant to more securely restrain the occupant.

Occupant restraint system with belt guide actuator

A seat belt system for a vehicle has a shoulder-belt extending diagonally across the seat. A belt tensioner applies tension to the belt in response to detection/prediction of a potentially unsafe situation by a safety sensor/control system. A support arm has an upper end mounted to the vehicle structure above an upper outboard portion of the seat. The support arm extends downwardly and a guide member is attached to the lower end of the support arm and engages the belt. The lower end of the support arm is movable relative to the upper end/mounting point such that when the tensioner is activated, the belt urges the guide member from a comfort position relatively far from the neck and/or upper shoulder of a seat occupant to a safety position closer to the seat.
