Patent number: 6283531Abstract: A vehicle comprises a vehicle body, an electric folding roof housed in the vehicle body in a folded state, an electric motor operate to unfold the folded electric folding roof, and a rigid roof designed to be attached to the vehicle body when the electric folding roof is folded and housed in the vehicle body. The vehicle also includes an inhibiting device for inhibiting operation of the electric motor upon detection of the attachment of the rigid roof to the vehicle body. With this arrangement, it becomes possible to prevent unfolding of the folded electric folding roof when the rigid roof is attached to the vehicle body. This leads to the further advantage that failure of the motor can be prevented.Type: GrantFiled: August 7, 2000Date of Patent: September 4, 2001Assignees: Honda Giken Kogyo Kabushiki Kaisha, Mitsui Kinzoku Kogyo Kabushiki KaishaInventors: Masahiro Tanigawa, Masanobu Shinoda, Jun Odahara, Tsuguo Hoshikawa
