Abstract: A head restraint (14) for helping to protect an occupant (60) of a vehicle seat (20) includes a base frame (150) connected to the vehicle seat. A cushion carrier (350) is supported on the base frame (150) by a track assembly (440) that facilitates movement of the cushion carrier (350) relative to the base frame (150) along a deployment axis (18) from a non-deployed condition to a deployed condition. The track assembly (440) includes a fixed track member (182) that forms a portion of the base frame (150). The fixed track member (182) includes spaced axially extending beam portions (190) with opposing surfaces (200) that define a channel (184) between the beam portions (190). The track assembly (440) also includes a sliding track member (370) that forms a portion of the cushion carrier (350).

Abstract: A seat belt retractor (10) includes a spool member (46) on which seat belt webbing (16) is wound. The spool member (46) is supported for rotation in a belt withdrawal direction (58) and an opposite belt retraction direction (60). The spool member (46) has an open end (56) and a closed end (54) spaced apart along the axis. A length of the spool member (46) extends from the open end (56) to the closed end (54). The spool member (46) is hollow and has a radially inner surface (102) and a radially outer surface (104). The radially outer surface (104) extends for the length of the spool member (46) and receives the seat belt webbing (16). The radially inner surface (102) extends for substantially the length of the spool member (46). A wall (106) of the spool member (46) is defined between the radially inner and outer surfaces (102, 104). The wall (106) has a thickness that is substantially constant along the radially inner surface (102).
