摘要:
A vehicle seat assembly that includes a seatback frame and an upper armature moveably supported by the seatback frame. The upper armature includes a head restraint and a first impact body, and the upper armature is operable to move in response to a predetermined force applied to the first impact body to thereby move the head restraint toward the occupant. The vehicle seat assembly also includes a lower armature that is operatively connected to the upper armature and is operable to move toward the upper armature in response to a predetermined force applied to the lower armature and act on the upper armature to move the head restraint toward the occupant.

A test assembly for evaluating vehicle head restraints comprises a carriage adapted to be coupled to a drive member capable of moving the test assembly, a head restraint coupled to the carriage and a manikin assembly having a head portion and a neck portion with an upper and lower end. The head portion couples to the upper end of the neck portion and the manikin assembly couples to the carriage at the lower end of the neck assembly. The head restraint is positioned adjacent the manikin assembly so that movement of the drive member causes the head portion of the manikin assembly to contact the head restraint. The manikin assembly may further include a load cell and accelerometer for evaluating the effectiveness and performance of a particular head restraint design.

摘要:
Multiple vehicle seats are disclosed with active head restraint systems that receive an input force from an occupant during an impact by a torso support, which consequently actuates a linkage that translates a head restraint upward and forward to the head of the occupant. In one embodiment, the torso support has a translatable connection with the seatback frame and another translatable connection with the linkage. In another embodiment, a torso support is pivotally connected to a pair of links which are each pivotally connected to the frame. In yet another embodiment, the seatback frame includes a structural wire, which provides pivotal connections for two of the links of the linkage.

A vehicle seat is disclosed with a seat back frame with a pair of spaced apart linkages connected to side members of the frame. A horizontally actuatable lumbar mechanism is connected to the pair of linkages for providing lumbar support to the occupant and for receiving an input force for actuating the linkages. A head restraint extends from the seat back frame and is operably connected to the frame and the pair of linkages such that actuation of the linkages actuates the head restraint from a design position to an actuated position. A flexible band lumbar support mechanism is provided. Also, a lumbar mechanism is provided with a pair of upright wires and a series of transverse suspension wires for supplying the back of the occupant and for distributing the input force during an impact.

An adjustable head restraint assembly for a vehicle seat is provided with a post for supporting a head restraint for movement along the post. A biasing member is mounted to the head restraint and cooperates with the post for maintaining the head restraint at a locked position. A ramp is fixed to the head restraint within a path of movement of the biasing member. An actuation member is mounted to the head restraint and cooperates with the biasing member for urging the biasing member into engagement with the ramp and consequently out of engagement with the post for permitting movement of the head restraint along the post.
摘要:
An infinitely adjustable head restraint assembly that includes a head restraint adapted for movement between a first position and a second position relative to a seatback of a vehicle seat assembly. The head restraint assembly also includes at least one biasing member that biases the head restraint away from the first position toward the second position. Furthermore, the head restraint assembly includes a retainer mechanism operable to retain the head restraint in any position between the first position and the second position and operable to release the head restraint for movement between the first position and the second position. The head restraint assembly can be incorporated in a vehicle seat assembly.

In one embodiment, a vehicle seat has a frame and is adapted to be mounted within a vehicle. The frame has first and second side members. The frame supports a head restraint that is moveable to an extended position providing support during an impact condition. An active head restraint system is connected to the head restraint for moving the head restraint when actuated. A cable is connected to the active head restraint. An impact member has a first end attached to the first side member, an intermediate portion spanning across a lumbar region and a second end extending to and not directly affixed to one of the first and second side members. The impact member is attached to the cable to translate upon receiving an input force from the occupant in response to the impact condition, displacing the cable and actuating the active head restraint system.

An adjustable head restraint assembly for a vehicle seat is provided with a pair of shells. Each shell is sized to mate with the other and collectively retain a pair of posts therebetween. A frame adapted to mate with the pair of shells for retaining the pair of shells upon the pair of posts. A locking mechanism is provided on at least one of the frame and the pair of shells for locking the pair of shells and the frame to the pair of posts, and for permitting adjustment of the pair of shells and the frame along the posts.
