Patent number: 7484797Abstract: A head rest of a vehicle seat may include a head support portion for supporting a head of a passenger, and a drive unit for moving the head support portion. The drive unit has a moving mechanism that is arranged and constructed to move the head support portion vertically and back and forth relative to the vehicle seat, a head detecting device provided to the head support portion so as to detect a clearance between the passenger head and the head support portion and to generate a control signal representative of the detected clearance, and a controller that can control the moving mechanism. The controller controls the moving mechanism so as to move the head support portion to a first proximity position in which the head detecting device may have a predetermined sensitivity relative to passenger head if the head support portion does not reach the first proximity position.Type: GrantFiled: December 27, 2005Date of Patent: February 3, 2009Assignees: Toyota Boshoku Kabushiki Kaisha, Fujikura Ltd.Inventors: Fumitoshi Akaike, Seiya Nishimura, Fumio Yajima, Nobumasa Misaki
