Problems solved by technology

[0003] According to the seat belt device of the above-mentioned prior art, when the guide device is rotated to the storage position, it is necessary to monitor the detection result of the vehicle speed detected by the vehicle speed sensor, and it is difficult to reduce the processing load, and it is difficult to reduce the size of the device and the device. The question of what constitutes the required fee
[0004] In addition, since the guide device cannot be stored until the vehicle speed reaches a predetermined speed or higher, if lateral acceleration or vibration acts on the vehicle body while the vehicle is running, the guide device will collide with the door, etc. and make a knocking sound. , causing discomfort to the occupants

Embodiment Construction

[0023] Hereinafter, a seat belt device according to an embodiment of the present invention will be described with reference to the drawings.

[0024] For example figure 1 As shown, the seat belt device 1 of the present embodiment is a so-called three-point seat belt device capable of restraining an occupant 3 seated on a vehicle seat 2 .

[0025] A webbing 5 drawn substantially vertically upward from a retractor 4 attached to a center column (not shown) is inserted into a through anchor 6 supported on the upper side of the center column. , and the front end of the webbing 5 is fixed to the underbody of the vehicle body via the seat belt guide 7 (seat belt guide mechanism) on the outside of the seat 2 .

[0026] The tongue 8 (tongue) of the webbing 5 inserted between the inserting fixture 6 and the seat belt guide 7 can be attached to and detached from the buckle 9 fixed on the vehicle body floor inside the seat 2 near the compartment.

[0027] The webbing 5 is wound around t...

Abstract

The invention provides a seat belt apparatus. A control device (43) controls driving of a motor (11) such that a clutch (12) of a power transmission mechanism (14) is moved to a disconnecting position and thereby a belt reacher device (7) is moved around in a forward direction of a vehicle by a return spring (7d) of the belt reacher device, if a change from an open state to a closed state of a door is detected by a door switch (55). The control device (43) controls driving of the motor (11) such that a webbing (5) is winded and thereby the belt reacher device is moved around to a retracted position in a backward direction of the vehicle, if a determination is made that no occupant seated in a passenger seat is detected by an output of an OFF signal from a buckle switch (51) of the passenger seat and a determination is made that start-up of the vehicle is detected by an output of an ON signal from an ignition switch (56).

Description

technical field [0001] The present invention relates to seat belt devices. Background technique [0002] Conventionally, for example, there has been known a seat belt device that rotates a guide (seat belt reacher) toward the front of a vehicle when an occupant sits on a vehicle seat, and turns When the buckle switch is turned off and the vehicle speed is above a predetermined speed, the guide device is stored (for example, refer to International Publication No. WO2011 / 152144). [0003] According to the seat belt device of the above-mentioned prior art, when the guide device is rotated to the storage position, it is necessary to monitor the detection result of the vehicle speed detected by the vehicle speed sensor, and it is difficult to reduce the processing load, and it is difficult to reduce the size of the device and the device. constitute the question of the cost required. [0004] In addition, since the guide device cannot be stored until the vehicle speed reaches a ...
