Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a belt anchor attachment structure for a cab-over type vehicle.

(Prior art and its problems) For example, as shown in Japanese Utility Model Application Publication No. 54-43713, a reinforcing member that can be attached and detached to the center of the floor under the driver's seat of a cab-over type car that has a service hole. It is known that the reinforcing member is provided with a parking brake lever.

Furthermore, as shown in FIG. 3, frames 12, 13, a belt anchor 14a and a parking brake 14b are installed on this frame 12, and a change operation device 1 is installed on the frame (bracket) 13.
5 is also known. Also, frame 1 is placed in the service hole 16 like this.
In the case where the frame 12 is constructed, the front end and the rear end of the frame 12 are generally attached to the floor 10 through fastening members such as bolts and nuts, respectively, in consideration of serviceability.

That is, in the case of the conventional one, the seat belt anchor attachment frame 1, which is both a rigid member,
2 and a reinforcing bracket 13 to which the change operating device 15 is attached are provided individually, and the seat belt anchor attachment frame 12 and the reinforcing bracket 13 are each individually designed to satisfy the required strength and rigidity. It was designed.

However, in this way, the seat belt anchor attachment frame 12 and the bracket 13 are
If they are arranged independently from each other, each element 12, 13 must have a predetermined strength, which causes problems such as the size and weight of each element 12, 13 increases. In particular, the required strength of the frame for attaching seat belt anchors needs to be set to a large value, taking into account that its role is to protect the human body in the event of a collision. Care must be taken to maintain the strength and rigidity of the material.

Under these circumstances, as described above, in the case where the seatbelt anchor attachment frame 12 is installed in the service hole 16, the force applied to the seatbelt anchor attachment frame 12 is transferred to the floor through its front end and rear end. 10, it is necessary to sufficiently increase the strength and rigidity of the seat belt anchor mounting frame 12 itself, which makes the problems of increasing size and weight even more remarkable. Ta. Furthermore, in cases where the front and rear ends of the seatbelt anchor attachment frame 12 are detachably attached using fastening members such as bolts and nuts, force is concentrated on the attachment seat of the seatbelt anchor attachment frame 12. Therefore, measures must be taken to improve the strength of this mounting seat.

Therefore, the purpose of the present invention is to increase the size and weight of a cab-over type vehicle, based on the structure of the belt anchor attachment part of a cab-over type vehicle, in which the seat belt anchor attachment frame is removably installed in the service hole. To provide a seat belt anchor mounting frame that effectively disperses the force applied to a reinforcing bracket for a change operating device, and improves the strength and rigidity of a mounting seat of the seat belt anchor mounting frame. It is in.

(Means and effects for solving the problem) The present invention focuses on the fact that in cab-over type vehicles, the seat belt anchor mounting frame and the reinforcing bracket for the change operating device are located close to each other. The reinforcing bracket for the change operating device is integrated with the frame for attaching the seat belt anchor, and the mounting seat portion of the frame for attaching the seat belt anchor is reinforced using the reinforcing bracket for the change operating device.

Specifically, the service hall is located approximately in the center of the floor below the driver's seat of cab-over type cars.
A belt anchor attachment part of a cab-over type vehicle, wherein a seatbelt anchor attachment frame extending in the front-rear direction is constructed, and the front and rear ends of the seatbelt anchor attachment frame are detachably attached to the floor via a fastening member. Assuming the structure, a reinforcing bracket for the change operating device fixed approximately at the center of the front descending floor continuous to the front of the floor is extended upward, and the upper end of this reinforcing bracket is connected to the seat belt anchor mounting frame. The front end of the front end is overlapped with the front end of the front end of the front end of the front end of the front end of the front end of the fastening member.

With this configuration, the belt anchor mounting frame and the change operating device reinforcing bracket, which are separate members, are integrated by the fastening member, so that the force applied to the belt anchor mounting frame is reduced by the change operation device. Needless to say, the force applied to the reinforcing bracket for the change operating device is also distributed to the belt anchor attachment frame, as well as being distributed to the reinforcing bracket for the operating device.
That is, the frame for attaching the belt anchor and the reinforcing bracket for the change operating device are in a complementary relationship with each other, and the dispersibility applied to each element is improved.

Further, the upper end of the reinforcing bracket for the change operating device also functions as a reinforcing member for the mounting seat portion of the seat belt anchor mounting frame.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

In Fig. 1, 1 is the floor below the driver's seat 2 of a cab-over type car.A service hall 3 is opened approximately in the center of the floor 1, and a floor 4 that extends downward from the front is formed continuously in front of the floor 1. has been done.

5 is a frame for attaching seat belt anchors, 6
indicates a reinforcing bracket, and a seatbelt (not shown) is attached to the seatbelt anchor attachment frame 5.
A seatbelt anchor 7a, a parking brake 7b, etc., which removably connect the terminals of the seatbelt anchor 7a and the like are attached to the seatbelt anchor attachment frame 5.
is provided on the center floor 1 next to the driver's seat 2, spanning the service hole 3 in the front-rear direction, and its rear end 5a is fixed to the floor 1 with bolts and nuts.

A reinforcing bracket 6 is fixed in the vertical direction on the back side of the floor 4, and a change operating device 8 is attached to this reinforcing bracket 6. The reinforcing bracket 6 is shaped to extend upward, and its upper end 6a
constitutes a mounting seat for the seatbelt anchor mounting frame 5 together with the floor 4, and the front end 5b of the seatbelt anchor mounting frame 5 is
The upper end 6a of the reinforcing bracket 6 overlaps with the upper end 6a of the reinforcing bracket 6, as shown in FIG. 2, and is integrally attached by a fixing member (fastening member) 9 made of bolts and nuts.

In the above configuration, the upper end 6 of the reinforcing bracket 6
Since a and the floor 4 form a mounting seat for the seatbelt anchor mounting frame 5, the strength and rigidity of the mounting seat are increased by the reinforcing bracket 6.

In addition, since the reinforcing bracket 6 and the seat belt anchor attachment frame 5 are integrally fastened together, the seat belt anchor Mounting frame 5 and reinforcement bracket 6
They will have a mutually complementary relationship. That is, the force applied to the seat belt anchor attachment frame 5 or the force applied to the reinforcing bracket 6 is also distributed to other elements. In particular, the large load applied to the seat belt anchor 7a,
The force is received by the seat belt anchor attachment frame 5 and the reinforcing bracket 6, and is finally dispersed to the floor 1. Therefore, the force dispersion of the seatbelt anchor attachment frame 5, which is constructed to be installed in the service hole 3, can be particularly improved.

As a result, even if the seat belt anchor attachment frame 5 or the reinforcing bracket 6 is made smaller than before, it is possible to maintain the same strength and rigidity as before, which is advantageous in terms of weight reduction. It can be made into something.

(Effects of the invention) As explained above, according to the invention, as a result of integrating the seat belt anchor mounting frame and the reinforcing bracket for the change operation device, both elements are in a mutually complementary relationship. It is possible to improve the dispersion of not only the force applied to the seat belt anchor attachment frame but also the force applied to the reinforcing bracket for the change operating device. Therefore, even if the seat belt anchor mounting frame or reinforcing bracket is downsized, sufficient strength and rigidity can be maintained.
It is possible to reduce the weight of the seat belt anchor attachment frame or reinforcing bracket.

Further, since the mounting seat portion of the seat belt anchor mounting frame is reinforced by the upper end of the reinforcing bracket for the change operating device, the strength and rigidity of the mounting seat can be improved.
