[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat belt mounting structure in a cab-over type vehicle, and more particularly to a structure in which a load applied to a seat belt at the time of a collision can be dispersed to prevent separation and deformation of a rear pillar.

[0002]

2. Description of the Related Art As a cab-over type truck,
For example, there is a panel van as shown in FIGS.
In general, the panel van 20 has a structure in which a cab-over type cab 21 is mounted on a front portion of a chassis and a box-shaped carrier 22 is mounted on a rear portion. The driver's cab 21 has a roof panel 23a, a front panel 23b, a side panel 23c, and a back panel 30 to form a driver's cab a, and a door 26 is provided at an opening formed in the side panel 23c so as to be openable and closable. Have been. The loading platform 22 forms a box-shaped luggage compartment b with a rear body front panel 30a, a rear body roof panel 30b, a rear body side panel 30c, and the like.
The sliding door 32 is disposed at the sliding door opening 0c. The back panel 30 divides the operator's cab a from the luggage compartment b, and the front edge of the sliding door opening is a rear body front pillar 31. When attaching the seat belt 27 to such a panel van 20, conventionally, the inner pillar 24 a of the rear pillar 24 of the cab 21 and the rein hose 24 b
The connection fitting 27a of the seat belt 27 is fastened to the joint portion with the bolt 28 by a bolt 28 and fixed. In the conventional mounting structure of the seatbelt 27, the rear pillar 24 and the rear body front pillar 31 are not specially connected only with the seal member 33 interposed therebetween. The applied load is received only by the rear pillar 24. Therefore, it is necessary to increase the thickness of the conventional rear pillar 24 so as to withstand the load. Therefore, a structure designed to allow the above load to be shared by other members without being burdened only by the rear pillars
Japanese Patent Application Laid-Open No. 52-68519 proposes a vehicle in which a seat belt is connected to a rear pillar, and the rear pillar and a guard frame of a carrier are connected by a connecting member.

[0003]

However, the mounting structure according to the above-mentioned prior art is a structure in which the load applied to the seat belt is once received by the rear pillar and then transmitted to the guard frame via the connecting member. Depending on the shape of the connection member, the connection structure, and the like, the load may not always be shared by both the rear pillar and the guard frame, and the rigidity of the rear pillar itself cannot be avoided. Therefore, there is a demand for a structural improvement so that the load can be shared more reliably.

The present invention has been made in view of the above-mentioned conventional situation, and provides a seat belt mounting structure for a cab-over type vehicle in which an impact force applied to a seat belt can be reliably shared by both a rear pillar and a rear body front pillar. It is intended to be.

[0005]

SUMMARY OF THE INVENTION The present invention provides a seat belt mounting structure for a cab-over type vehicle in which a cab is disposed behind a cab-over type cab, and a back panel of the cab and a front panel of the cab. And a sealing member made of an elastic member interposed therebetween, and one end and the other end of a belt anchor curved in the vehicle width direction are connected to the rear pillar of the cab and the support of the gantry by bolting, so that the cab and the gantry can be connected to each other. And the seat belt is fixed to the belt anchor.

[0006]

According to the cab-over type seat belt mounting structure of the present invention, the rear pillar and the support of the carrier are connected by the belt anchor, and the seat belt is connected to the anchor, so that the seat belt is added to the seat belt at the time of collision. The load is directly distributed to the rear pillar and the support via the belt anchor. Therefore, the load on the rear pillar can be reduced as compared with a structure in which the load is once received by the rear pillar and transmitted to the guard frame as in the above-mentioned conventional publication, and as a result, the rigidity of the rear pillar does not need to be increased so much.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIGS. 1 to 3 are views for explaining a seat belt mounting structure of a cab-over type vehicle according to an embodiment of the present invention. In this embodiment, a case where the invention is applied to a panel van will be described. In the figure, reference numeral 1 denotes a panel van to which the structure of the present embodiment is applied, which is configured by disposing a box-shaped carrier 3 behind a cab-over type cab 2. The driver's cab 2 includes a roof panel 2a, a side panel 2b, a front panel 2c, a back panel 5, and the like, and forms an operator's cab a, and a door 4 is provided at a door opening of the side panel 2b so as to be freely opened and closed. ing.

The loading platform 3 forms a box-shaped luggage compartment b with a rear body front panel 3a, a rear body roof panel 3b, a rear body side panel 3c and the like, and has a wide width formed in the rear body side panel 3c. The slide door 3d is provided at the slide door opening so as to be freely opened and closed. The front edge of the sliding door opening of the rear body side panel 3c is a rear body front pillar 3e extending vertically, and the back panel 5 of the cab 2 separates the cab a and the luggage compartment b. doing.

The rear pillar 2d constituting the rear edge of the door opening of the side panel 2b has a closed cross-section composed of an inner pillar 6 and an outer pillar 7, and a rein hose 8 is provided between the pillars 6,7. It is arranged. The front end flange portions 6a and 7a of the pillars 6 and 7 are spot-welded with the front end flange portion 8a of the rein hose 8 therebetween. The rear end flange portion 6b of the inner pillar 6 is spot-welded to the back panel 5, and the rear end flange portion 7b of the outer pillar 7 and the rear end flange portion 8b of the rein hose 8 are connected to the outer flange portion of the back panel 5. It is spot welded together with 5a.

The rear body front pillar 3e has a closed cross-section comprising an inner panel 9, an outer panel 10 and a side edge 3f of the rear body front panel 3a, and each rear end flange of the inner panel 9 and the outer panel 10 is provided. 9b and 10b are spot-welded to each other, and the front end flange 9a of the inner panel 9 is spot-welded in the middle of the side edge 3f. A weatherstrip 12 is mounted on the opening flange 3g of the front panel 3a, and the weatherstrip 12 is pressed against the back panel 5 so that a space between the operator's cab a and the luggage compartment b is provided. Is sealed.

A reinforcing plate 15 having a substantially L-shaped cross section is spot-welded to the outer surface of the rear body front panel 3a. Three nuts 15a are welded to the plate 15 at intervals in the vertical direction.
A bead portion 15b is formed between the nuts 15a. A substantially L-shaped reinforcing bracket 16 is spot-welded to a portion of the inner surface of the rear body front panel 3a facing the plate 15, and a portion of the bracket 16 facing the nut 15a. Is formed with a bolt insertion hole 16a.

The rear pillar 2d and the rear body front pillar 3e are connected by a belt anchor 17. The belt anchor 17 is provided at the rear end of a curved connecting portion 17b extending from the luggage compartment b through the opening 5b formed in the back panel 5 into the cab a.
, And an anchor portion 17c at the front end, which is in contact with the inner surface of the inner pillar 6, is integrally formed, and a bead portion 17f is formed at the connecting portion 17b. In addition, the flange portion 17a
A bolt hole 17 d communicating with each bolt insertion hole 16 a of the bracket 16 is formed in the bracket 16.
d, The bolt 14 is inserted into the insertion hole 16a. The bolt 14 penetrates through the rear body front panel 3a and is screwed into the nut 15a, so that the flange portion 17a, the bracket 16,
5, and the rear body front panel 3a are fixedly fastened together. Further, the mounting hole 1 is provided in the anchor portion 17c.
