Description

The present invention relates to an improved seat cushion mounting structure in a cab-over type vehicle.

b. Prior Art In this type of vehicle, a seat cushion c is detachably attached to a raised portion b of a floor panel a as shown in FIG. Inspection and repair of the engine is performed after removing the engine. FIG. 4 is a sectional view showing an example of the mounting structure, in which d is a cabback, and e is an engaging member provided at the rear end of the seat cushion c. Then, the engaging member e is inserted into the hole f of the cab back d, and the front end of the seat cushion c is fixed to the floor panel a by the fixture g.
It is fixed to. This fixture g is a seat cushion c
A base h fixed to a floor panel a as a lock member, a lever j rotatably supported by the base i, and a ring provided at the base of the lever j The seat cushion c is pressed and fixed to the floor panel a by hanging the ring k on the hook h and rotating the lever j counterclockwise.

c. Problems to be Solved by the Invention However, according to the above structure, since the rear portion of the seat cushion c is the one in which the engaging member e is inserted into the hole f of the cab back d, rattling occurs, and the engine room There was a problem that the sealability was poor.

Further, the mounting position of the seat cushion is easily shifted back and forth, and in that case, there is a disadvantage that a large force is required to operate the lever of the fixture g.

d. Means for Solving the Problems The present invention has been made in view of the above problems, and an object of the present invention is to provide a mounting structure of an automobile seat cushion that can securely fix a seat cushion, The gist is that in a mounting structure in which a seat cushion is detachably fixed to a floor panel of an automobile, the seat cushion includes an engaging member having a shaft portion extending in a lateral direction of a vehicle body at a rear end portion. A fixing portion fixed to the floor panel and a rotating portion for rotatably holding the engaging member on the floor panel. A hinge having a U-shaped cross-section in which a notch is formed and the shaft-like portion can be inserted is provided in a pivoting portion of the hinge, and a front-inclined inclined surface is formed in a fixing portion of the hinge. Having insertion A support wall having a surface and a regulating surface that rises in a substantially vertical direction is provided,
When the insertion surface is at a predetermined inclination angle of the holding wall,
When the shaft portion is flush with the wall surface of the holding wall so that it can be inserted into the holding wall, when the holding surface holds the shaft portion and holds down the holding wall in the horizontal direction, The seat cushion penetrates the notch formed in the holding wall and regulates the forward movement of the shaft portion. The relative positional relationship between the holding wall and the support wall makes it possible to prevent the shaft portion from coming off. An upward hook is attached to the front of the vehicle, and a seat cushion can be locked by a lock member provided on the floor panel.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, reference numeral 1 denotes a seat cushion, 2 denotes a floor panel, and 3 denotes a gab back. At the rear end of the seat cushion 1, in the center in the left-right direction,
An engaging member 4 having a shaft shape and a U-shaped cross section protrudes. In addition, a connecting tool 5 as a hinge mechanism is fixed to the floor panel 2. The connecting tool 5 includes a base 6 fixed to the floor panel 2, a holding wall 7 having a U-shaped cross section on the rotating side hinged to the base 6, and a support wall 8 erected on the base 6. It consists of. A notch 9 is provided in the center of the holding wall 7. When the holding wall 7 is raised as shown in FIG. 1, the upper end of the support wall 8 fits in the notch 9. In addition,
The front wall of the holding wall 7, which is formed in a U-shape with the opposing walls, is provided with a cutout 9 except for the upper part thereof.

On the other hand, the support wall 8 is provided with an insertion surface 8b having a front inclined surface, and the insertion surface 8b is formed on the seat cushion when the holding wall 7 is at a predetermined inclination angle, as shown in FIG. The fixed engaging member 4 is the same as the wall surface of the holding wall 7 so that it can be inserted into the holding wall 7. The support wall 8 is provided with a regulating surface 8c which rises substantially in the vertical direction. As shown in FIG.
When the holding wall 7 is tilted in the horizontal direction, the holding member 7 penetrates the notch 9 (see FIG. 1) formed in the holding wall 7 and restricts the forward movement of the engaging member 4. I have. That is, the engagement member 4 can be removed and prevented from being removed by the relative positional relationship between the holding wall 7 and the support wall 9.

When attaching the seat cushion 1 to the floor panel 2, first, as shown in FIG. 2, the engaging member 4 of the seat cushion 1 is inserted into the holding wall 7 of the connecting member 5 from obliquely above. The front surface of the seat cushion 1 may be fixed to the floor panel 2 by the fixture g shown in FIG. At this time, the engaging member 4 is fitted and locked on the bottom of the sandwiching wall 7 and the bottom 8a of the support wall 8, and the seat cushion 1 is locked.
Will be positioned in the front-back direction.

Since the present embodiment is configured as described above, the seat cushion 1 can be securely fixed to the floor panel 2, and rattling does not occur at the rear of the seat cushion 1 as in a conventional mounting structure. Absent.

Further, when the seat cushion 1 is tilted, the bottom 8a of the support wall 8 and the bottom of the sandwiching wall 7 lock the shaft of the engaging member, and accurate positioning in the front-rear direction is performed. Operation is not difficult.

Note that the seat cushion 1 does not come off the floor panel 1 during traveling even if the lock is released from the fixture g or the user forgets to lock the lever j.

e. Effects of the Invention According to the present invention, the seat cushion engaging member is rotatably supported on the floor panel by the hinge via the bottom of the sandwiching wall and the bottom of the support wall. Can be securely fixed, and the rear portion of the seat cushion does not rattle as in the conventional mounting structure, and the sealing performance of the engine room does not deteriorate. Since the front part of the seat cushion is fixed by the hook and the lock member, rotation of the seat cushion can be prevented.

Further, the relative position between the holding wall and the support wall of the hinge enables the engagement member to come off and prevent the shaft portion from coming off, so that the seat cushion can be attached and detached extremely easily.
