Vehicle headrest apparatus
First Claim
1. A vehicle headrest apparatus comprising:
- a headrest portion with a mounting member configured to be mounted to an upper end part of a seatback;
a head restraining member including a vertical support portion arranged to face towards a passenger'"'"'s head and a horizontal support portion arranged substantially perpendicular to the vertical support portion; and
a tensioning device operatively coupled to the head restraining member to apply tension to at least part of the vertical support portion when a rear-end collision occurs.

Abstract
A vehicle headrest apparatus has a headrest unit that is mounted to an upper end of a seatback. The headrest unit has a head restraining member with a flexible sheet restraining member configured to be tensioned to restrain a passenger'"'"'s head when a controller detects a rear-end collision. The head restraining member has a vertical support portion facing the head of the passenger and a horizontal support portion substantially perpendicular to an upper part of the vertical support portion. When a rear-end collision occurs, tension is applied to at least the vertical support portion. In some embodiments, the vertical and horizontal support portions are both formed by the flexible sheet restraining member. In other embodiments, only the vertical support portion is partially formed by the flexible sheet restraining member, and the vertical and horizontal support portions are made of a resilient material having an excellent shape-retaining property.

30. A vehicle headrest apparatus comprising:
-
a headrest portion including left and right headrest members dividing the headrest portion approximately midway in a transverse direction and a mounting member configured to swingably couple the left and right headrest members to an upper end part of a seatback;
a head restraining member moveably coupled between the left and right headrest members, the head restraining member including a vertical support portion arranged to face towards a passenger'"'"'s head and a horizontal support portion arranged substantially perpendicular to an upper edge of the vertical support portion, at least one of the horizontal and vertical support portions being made of a resilient shape-retaining material;
a swing force applying device operatively coupled to the left and right headrest members to apply an urging force to the left and right headrest members to swing the left and right headrest members toward a front of a vehicle;
a lock device operatively coupled to the left and right headrest members to hold the left and right headrest members in an initial storage position against the urging force applied by the swing force applying device;
a controller operatively coupled to the lock device to release the lock device upon detecting a rear-end collision; and
a tensioning device operatively coupled to the vertical support portion to apply tension in at least part of the vertical support portion of the head restraining member when the left and right headrest members are in a swung forward state and to reduce deflection of the vertical support portion during elastic deformation of the vertical support portion. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A vehicle headrest apparatus comprising:
-
headrest means for mounting to an upper end part of a seatback;
vertical head restraining means for supporting a passenger'"'"'s head when a rear-end collision occurs;
horizontal vertical head restraining means for supporting a passenger'"'"'s head when the rear-end collision occurs, the horizontal vertical head restraining means being arranged substantially perpendicular to the vertical support portion; and
tensioning device means for applying tension to at least part of the vertical head restraining means when the rear-end collision occurs.
