Claims

[Scope of utility model registration request]

A slide anchor is attached to the tip of the occupant restraint webbing, and a guide rail is installed on the vehicle body around the door to guide the slide anchor.The slide anchor is guided by the guide rail and moves by motor drive, and the webbing is automatically attached to the occupant. A control device for an automatic seat belt device that is installed and released includes a position detection means for detecting the position of a slide anchor, and a motor that is driven at a low speed by chopper control when the slide anchor is located within an upper passenger getting on/off section. , comprising a control means that continuously energizes the motor to drive it at high speed when the slide anchor is located in a movement section outside the section, and stops the motor when the slide anchor is in the webbing release position. automatic seat belt control device.
