Patent number: 6698795Abstract: A seat belt system for a vehicle, for restraining an occupant in a seat disposed in a compartment of the vehicle. The vehicle comprises an opening formed on at least one side of the vehicular body, and a first door moving between a first state where the first door closes at least a part of the opening and a second state where the first door opens the opening. The seat belt system includes a belt webbing, a retractor disposed in the first door for retracting the proximal end of the belt webbing, and a sliding device fixed on a lower edge of the opening, to which the distal end of the belt webbing is attached. The sliding device permits the distal end of the belt webbing to slide along the lower edge of the opening between a forward position and a rearward position. The distal end of the belt webbing is located at the rearward position when the first door is in the second state.Type: GrantFiled: March 28, 2002Date of Patent: March 2, 2004Assignee: Mazda Motors CorporationInventors: Hiroaki Enomoto, Kouji Kishino, Takashi Mizuma
