Patent number: 7070205Abstract: The headrest of an automotive vehicle seat has at least one bar (20) and one supporting member (26). Normally, the supporting member (26) is in a utilization position. When the automotive vehicle is involved in an accident, the supporting member (26) leaves the utilization position and adopts an accident position in which it is located in front of the utilization position. The at least one bar (20) comprises an oblique portion (30) that is located above an upper edge (32) of a backrest of the automotive vehicle seat. Said oblique portion has one component in the x direction and one component in the z direction. The supporting member (26) comprises a guide region (34) that conforms to the oblique portion (30) of bar (20) and that is movable relative to the oblique portion (30). An elastic means (spring 48) biases the supporting member (26) in the accident position. A releasable locking device (52) is associated with the elastic means, which it normally blocks.Type: GrantFiled: March 5, 2004Date of Patent: July 4, 2006Assignee: C. Rob. Hammerstein GmbH & Co.
