Abstract

PURPOSE:To positively fix a seat cushion to the floor and facilitate loading and unloading of it by providing a hinge mechanism permitting turning of the seat cushion with an engaging member being engaged in a fixture provided on the floor so that the engaging member can be loaded and unloaded. CONSTITUTION:When a seat cushion 1 is mounted to a floor panel 2, an engaging member 4 of the seat cushion 1 is first inserted from above slantly into a holding wall 7 of a connecting fitting 5, the seat cushion 1 is then laid down forward and its underside is abutted on the floor panel 2, and the front end part of the seat cushion 1 is fixed to the floor panel 2. At this time, the engaging member 4 is fitted into a bottom part 8a of a supporting wall 8, and the seat cushion is positioned in front and in rear directions. The seat cushion 1 is thus positively fixed to the floor panel 2, and the possibility of generation of backlash as before in the rear part of the seat cushion 1 can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to an improvement in the mounting structure of a seat cushion in a cab-over type vehicle.

b. Prior Art In this type of vehicle, a seat cushion C is removably attached to a raised portion of a floor panel a, as shown in FIG. The engine is inspected and repaired after it is removed.

FIG. 4 is a sectional view showing an example of the mounting structure, and d
is a cab back, and e is a retaining 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 with the fixture g. This fixture g
consists of a hook h protruding from the front end of the seat cushion C, a base i fixed to the floor panel a, a lever j rotatably supported on the base i, and a hook h provided at the base of the lever j. The seat cushion C is fixed to the floor panel a by pressing the ring k onto the hook h and rotating the lever j counterclockwise.

C0 Problems to be Solved by the Invention However, according to the above structure, since the retaining member e is a hole inserted into the hole f of the cab back d at the rear of the seat cushion C, it rattles and causes damage to the engine compartment. There was a problem with poor sealing performance.

Also, the mounting position of the seat cushion tends to shift back and forth,
In that case, there was also a drawback that a large force was 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 its purpose is to provide a mounting structure for an automobile seat cushion that can securely fix the seat cushion. The gist is that in a mounting structure in which a seat cushion is removably fixed to the floor of an automobile, a retaining member is provided protruding from the end of the seat cushion, and a connector for attaching and detaching the retaining member is attached to the floor. The present invention provides a mounting structure for a seat cushion of an automobile, characterized in that the connector is provided with a hinge mechanism that allows the seat cushion engaged with the engagement member to rotate.

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

In Figures 1 to 3, 1 is a seat cushion;
2 is the floor panel and 3 is the cab back. At the rear end of the seat cushion l, an engagement member 4 having a U-shaped cross section is protruded from the center in the left-right direction. Also floor panel 2
A connector 5 is fixedly attached to the holder. This connector 5 is composed of a base 6 fixed to the floor panel 2, a holding wall 7 having a zero-shaped cross section hinged to the base 6, and a support wall 8 erected on the base 6. be. In addition, in the center of the holding wall 7,
A notch 9 is provided, and when the clamping wall 7 is raised as shown in FIG. 1, the supporting wall 8 is accommodated in this notch 9. Note that the front wall of the holding wall 7, which is formed into a U-shape consisting of opposing walls, is provided with a notch 9 leaving an upper portion thereof.

When attaching the seat cushion 1 to the floor panel 2, first, as shown in FIG.
Insert the engaging part 4 of the seat cushion 1 from diagonally above,
Next, the seat cushion 1 is tilted forward so that its lower surface is brought into contact with the floor panel 2, and the front end of the seat cushion 1 is fixed to the floor panel 2 using the fixture g shown in FIG.

At this time, the retaining portion 4 fits into the bottom portion 8a of the support wall 8, and the seat cushion 1 is positioned in the front-rear direction.

Since this embodiment is configured in this way, the seat cushion 1 can be securely fixed to the floor panel 2,
Unlike conventional mounting structures, there is no wobbling at the rear of the seat cushion I.

Further, when the seat cushion l is folded down, accurate positioning in the front and rear direction is achieved, so it is not difficult to operate the lever of the fixture g.

Note that even if the fixing device g lock comes off or the user forgets to lock the lever j, the seat cushion l will not come off from the floor panel 1 while the vehicle is running.

e. Effects of the Invention According to the present invention, since the seat cushion is rotatably supported on the floor via the connecting tool, the seat cushion can be securely fixed to the floor, and the seat cushion can be fixed to the floor without any problem in the conventional mounting structure. There will be no rattling at the rear of the cushion and the sealing performance of the engine compartment will not deteriorate.

Further, since the connecting member is configured so that the retaining portion of the seat cushion can be attached and detached and the seat cushion can be rotated, the seat cushion can be attached and detached very easily.
