Abstract

The present invention provides a seat belt control device (200) for giving a seat occupant an appropriate somatosensory alarm based on the seat belt. The seat occupant is given a somatosensory alarm based on the change in the closeness of the seat occupant. The somatosensory alarm control unit is configured to include: an adaptation action implementation unit (202), which implements an adaptation action, and controls the time for the motor to rotate forward based on the motor current value when the motor (5) is rotated forward, so that the seat belt is tightly attached. Degree control is the initial seat belt tightness; and the body-sensing alarm action implementation part (203), implements the body-sensing alarm action, repeats the forward rotation of the motor so that the seat belt tightness is gradually improved from the initial seat belt tightness At least one of the rotation action, the braking action that puts the motor in the short-circuit braking state, or the reverse action that makes the motor reverse, and the adaptation action is performed before the somatosensory alarm action is implemented.

Description

technical field

[0001] The present invention relates to seat belt control devices. Background technique

[0002] Patent Document 1 discloses, as a conventional seat belt control device, a configuration capable of increasing or decreasing the tension of a seat belt (webbing) for restraining a seat occupant of a vehicle by repeating a plurality of times. The seat belt control device performs the operation of the seat belt, that is, alternately repeats the winding operation and the drawing operation of the seat belt, and provides a sensory alarm based on the seat belt to the seat occupant.

[0003] Patent Document 1: Japanese Patent Laid-Open No. 2007-022400

[0004] However, the above-mentioned conventional seat belt control device is configured so that the amount of seat belt winding by the seat belt winding operation in the initial stage of the sensory alarm is larger than that in the later stage of the sensory alarm. Winding amount.

[0005] The tightness of the seat bel...
