Description

  The present invention relates to a mounting structure for an automobile seat belt retractor.

  Seat belts play an important role in protecting passengers from vehicle crashes. Recent seat belts are designed to be retracted by a retractor when not in use. As a function of the seat bell retractor, in addition to the original function of retracting the seat belt, a vehicle collision or a collision is predicted. Sometimes, a pretensioner mechanism that winds up a seat belt has been put into practical use, and the retractor tends to be enlarged.

  In a general vehicle such as a passenger car, the seat belt retractor is attached to the side of the seat, that is, the side of the vehicle body (for example, a pillar). However, in a special vehicle, for example, a two-theta / open top type automobile, it is difficult to find an appropriate rigid member in the vicinity of the seat that is sufficient to support a seat belt retractor on which a large tensile load acts upon a collision.

  Patent Document 1 proposes to attach a seat belt retractor to a roll bar (guard bar). According to this, since the roll bar is a member that protects the occupant when the vehicle falls, it has the ability to support the seat belt retractor to which a large pulling force acts upon a collision.

The two-theta / open top type automobile has a kick-up portion extending obliquely upward and rearward in the vicinity of the back of the seat from the rear end of the front floor portion constituting the floor surface of the passenger compartment as a body structure. A closed cross section is formed at the upper end by a cross member extending in the vehicle width direction. Patent Document 2 proposes that a reinforcement is provided in the cross member, and a seat belt retractor is attached to the reinforcement.
JP-A-5-58240 JP-A-4-342672

  However, as in Patent Document 1, when the seat belt retractor is attached to the roll bar, even if the seat belt retractor is covered with the trim, the seat belt retractor has a tendency to be enlarged, and thus the design of the trim is greatly affected. It will be a factor, and it will be greatly restricted in terms of appearance. Needless to say, the technique disclosed in Patent Document 1 cannot be applied to a vehicle that does not include a roll bar.

  In addition, as in Patent Document 2, when a reinforcement is provided on the closed cross section of the upper end of the kick-up portion and the seat belt retractor is attached to the reinforcement, when the seat belt retractor is relatively small, There is no problem, but the design margin is small for the enlargement of the seat belt retractor. That is, when a large seat belt retractor is attached, the reinforcement must be enlarged, and the cross member must also be enlarged.

  The present invention has been devised in consideration of the above situation, and its purpose is to provide an appropriate rigid member to which a seat belt retractor such as a 2-theta / open top type vehicle can be attached in the vicinity of the seat. An object of the present invention is to provide a mounting structure for a seatbelt retractor for an automobile that can attach a seatbelt retractor in the vicinity of a seat without requiring a reinforcing structure even for a vehicle that is difficult to find.

  It is a further object of the present invention to provide a mounting structure for an automobile seat belt retractor that can accommodate an increase in the size of the seat belt retractor without significantly changing the basic design of the automobile body.

According to the present invention, such a technical problem is
A front floor to which seats are attached;
A kick-up portion extending obliquely upward and rearward along the back surface of the seat from the rear end of the front floor portion;
A rear floor portion extending rearward from the upper end of the kick-up portion;
The front floor portion, kick-up portion, is provided so as to extend in the longitudinal direction of the vehicle body on both sides of the lower surface of the rear floor portion, said front floor portion, kick-up portion, a closed cross section extending in the vehicle longitudinal direction between the rear floor section In the mounting structure of an automobile seat belt retractor comprising a frame to constitute ,
A retractor bracket of the seat belt retractor is fastened together with a kick-up portion and a joint portion of the frame forming a closed cross section extending in the longitudinal direction of the vehicle body by fastening means. This is achieved by providing a mounting structure.

  That is, according to the present invention, the retractor bracket is fastened together with a fastening means such as a bolt, for example, to a portion where the frame of the vehicle body strength member is located in the kick-up portion having low rigidity as a whole. Thus, the seat belt retractor can be supported using the rigidity of the frame. Therefore, it is possible to support the seat belt retractor against the pulling force acting at the time of collision without separately preparing a reinforcing member.

  In a preferred embodiment of the present invention, an opening is provided in the kick-up portion, and a seat belt retractor is disposed on the back side of the kick-up portion through this opening. According to this, since the seat belt retractor is disposed outside the passenger compartment, it is possible to sufficiently cope with an increase in the size of the seat belt retractor. The frame on which the retractor bracket is fastened together by the fastening means may be a front frame extending along the kick-up portion from the front floor portion, or a rear frame extending rearward from the kick-up portion.

  In a preferred embodiment of the present invention, the rear frame has a sub-frame that extends downward in an arch shape, the front end of the sub-frame is joined to the kick-up portion, and the retractor bracket is fastened together by fastening means at the joint portion. Is done. When the seat belt retractor is disposed on the back side of the kick-up portion through the opening of the kick-up portion, the sub-frame is located in the lower region of the seat belt retractor, so that The seat belt retractor can be protected by the frame. In a preferred embodiment, a seat belt retractor is disposed in a space closed by side wall panels on both sides of the subframe, and the seat belt retractor is covered with a cover member. As a result, the seat belt retractor can use a space that would otherwise be a dead space, and since this space is wide, it can easily cope with an increase in the size of the seat belt retractor. In addition, the intrusion of dust and running sound from the outside through the opening of the kick-up portion can be reduced by the double barrier of the side wall panel and the cover member.

  When a rear end joining flange joined to the kick-up portion is provided at the rear end of the seat bracket for attaching the seat, the lower end portion of the retractor bracket including the rear end joining flange is fastened together with the fastening means. It is good. Since the seat bracket generally has a three-dimensional solid shape, the support rigidity of the seat belt retractor can be improved by using the seat bracket.

  The present invention is most preferably applied to an open top type automobile having a retractable roof. According to the present invention, since the seat belt retractor is not attached to the roll bar as in the prior art, the seat belt retractor is disposed at the kick-up portion which is a portion that does not affect the storage of the roof. There is an advantage that the storage property of the roof and the close arrangement of the sheet and the roll bar are not affected.
