Description

The present invention relates to a vehicle seatbelt support device for supporting a front seatbelt.

(Prior Art) Conventionally, various structures have been adopted for a seat belt supporting device of this type of vehicle. For example, the actual exploitation Sho 57-51959
In those disclosed in Japanese Laid-Open Patent Publication No. 56-135756 and Japanese Utility Model Laid-Open No. 56-135756, a belt guide for supporting a shoulder belt is fixed to one side of a seat back or a headrest of a front seat. Further, in the one disclosed in Japanese Utility Model Laid-Open No. 54-22724, the discomfort that the upper part of the shoulder belt touches the occupant's neck is eliminated, and the initial load acting on the occupant via the shoulder belt at the time of collision is reduced. For this reason, a belt guide that supports the shoulder belt is attached to the upper part of the seat back of the front seat or to the side of the headrest via a support arm having flexibility in the vehicle front-rear direction and the vehicle interior direction.

(Problems to be solved by the invention) By the way, in order to reduce the amount of seat belts visible on the belt line and improve the appearance, the applicant has provided a seat belt retracting member for the front seat shoulder belt on the rear door panel. Another application is filed in which the shoulder belt for the front seat unwound from the seat belt winding member is made to extend in the front seat direction via a door side belt guide provided on the rear door.

However, when the above conventional structure is adopted for such a vehicle, when the seat belt retracting member is locked,
In the case where the above-mentioned belt guide is fixed, since the seat belt length between the seat belt retracting member and the tongue plate of the shoulder belt is fixed, if the rear door is opened in this state, If the opening angle is restricted and the rear door is forcibly opened wide, the shoulder belt is pulled toward the outside of the rear vehicle and bites into the front seat occupant, causing an unnecessarily large load on the front seat occupant. It will give a feeling of pressure. Further, even in the case where the belt guide is attached by a flexible support arm, since the flexibility is limited in the front-rear direction of the vehicle body, the same problem as the former is caused.

The present invention has been made in view of the above point, and is a vehicle seat belt supporting device in which a door side belt guide to which a front seat belt is anchored is provided in a vehicle rear seat door. It is an object of the present invention to enable the opening operation of the rear seat door without giving a feeling of pressure to the front seat occupant even when the opening operation is performed.

(Means for Solving the Problems) In order to achieve the above object, the solution means of the present invention is such that a seat side belt guide is disposed on the vehicle outer side of a seat back shoulder portion of a front seat, and the seat side belt guide is provided. It is assumed that the vehicle seatbelt support device has the front seatbelt inserted therethrough. The seat belt for the front seat is anchored to a door-side belt guide provided on the rear seat door.
Between the one end and the other end of the front seat belt, at least the seat side belt guide and the door side belt guide are guided so as to pass through a predetermined path. It is assumed that adjustment means is provided for changing the path of the seat belt for the front seat to a path having a path length shorter than the predetermined path when the rear seat door is opened.

(Operation) According to the above configuration, when the rear seat door is opened, a tensile load that acts to extend its path length acts on the front seat belt with the operation of opening the rear seat door. Although it acts as a weighted load on the front seat occupant, when the rear seat door is opened, the seat belt for the front seat is guided by the seat belt guide and the door belt guide by the adjusting means. Is changed to a route in which the route length is shortened, so that the front seat occupant will not be squeezed by the seat belt.
