Abstract

An occupant protection system includes arm rests that are disposed on first and second width direction sides of a seat back and are rotatable between a substantially vertical storage position and a substantially horizontal use position; slide members that are slidable along the arm rests and have belt guides; a retractor that takes up webbing of a belt; and an electronic control unit that, (i) in a state before an occupant is seated in a vehicle seat, causes the arm rests to be held in the storage position and causes the slide members to slide in the seat upward direction above the head of the occupant, and that, (ii) when the occupant is seated, causes the arm rests to rotate to the use position, causes the slide members to slide toward base sides of the arm rests, and causes the webbing to be taken up by the retractor.

Description

technical field [0001] The present invention relates to a vehicle seat belt device and an occupant protection device. Background technique [0002] Japanese Patent Application Laid-Open No. 2009-279985 discloses a structure in which a motor mounted on a vehicle seat and a motor mounted on a A structure in which the roll-up parts on the top are connected by cables in the vertical direction of the seat. In addition, a joint movable in the seat up and down direction along the cable is provided, and a seat belt (webbing) whose end portion is fixed to the roof is spanned over the joint. Moreover, this seat belt adopts a structure in which the joint is arranged on the roof side of the vehicle in the state before being worn, and the joint is driven to the vehicle seat by driving the motor after the occupant sits on the vehicle seat. The underside of the seat is moved so that the seat belt is worn. [0003] However, in the technique described in Patent Document 1, one end portion...
