Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a seat device for a cab-over type vehicle that can correct dimensional errors in the distance between the lock lever and the hook during assembly of the vehicle body. be.

(Prior Art) In the case of cab-over type automobiles, the service hole formed in the floor panel must be opened when inspecting and servicing the engine, so the seat on the floor panel is provided so as to be rotatable upward on the rear side. At all times, it is locked to the floor panel with a latch so that it cannot rotate. Conventionally, such a seat device is also shown in Japanese Utility Model Application No. 57-177845, but in this case, the hook is attached to the lower front end of the seat cushion, and the lock lever is attached to a base plate provided on the floor panel. Since the seat is attached, there is a dimensional error in the distance between the hook and the lock lever during assembly, which may result in the seat not being properly locked and causing the seat to wobble.

(Purpose of the invention) The present invention is to improve the drawback that dimensional errors occur between the hook and the lock lever when assembling the conventional seat device, and even if dimensional errors occur, adjustments can be made accordingly. The purpose is to provide a car seat device that can be easily made.

(Structure of the invention) In the present invention, a seat is arranged on the upper surface of a floor panel of a vehicle body, a base plate is attached to the floor panel, and a lock lever is coupled to the base plate so as to be freely rotatable in the vertical direction. A latch is provided between the lock lever and a hook provided on the seat cushion to connect them, and a rotatable adjuster is provided on the side of the latch that connects to the hook. For the child,
A plurality of locking surfaces having different lengths in the radial direction with respect to the center of rotation are formed, and the locking surfaces and the hook are connected via a fixing groove and fixed, whereby the hook and the lock lever are connected. The structure is such that the dimensional error in the interval between the two is corrected.

(Example) The present invention will be explained below based on examples.

In FIG. 1, reference numeral 1 denotes a seat, and the seat 1 consists of a seat cushion 1a and a seat back 1b, and is arranged on the upper surface of a floor panel 2.

FIG. 2 is an enlarged view of the main parts of the present invention, in which a base plate 3 is placed in front of the stepped portion 2a of the floor panel 2.
is installed. A lock lever 4 is coupled to the base plate 3 by a pin 5 so as to be rotatable in the vertical direction (directions of arrows A and B). or,
A hook 6 is attached to the seat cushion 1a. A latch 7 that can be freely engaged and detached from a hook 6 is rotatably attached to the lock lever 4, and a rotatable adjuster 8 is provided on the side of the latch 7 that connects to the hook 6. A plurality of locking surfaces 8a, 8b, 8c, and 8d having different lengths in the radial direction with respect to the center of rotation are formed on the adjuster 8, and a plurality of fixing grooves 9 are formed on both ends of the adjuster 8. is formed.

With the above configuration, when the lock lever 4 is rotated about the pin 5 in the direction of arrow B in FIG. When the distance S1 between the center of rotation and the hook 6 is short, a gap S2 is created between the hook 6 and the adjuster 8. To absorb this gap, the adjuster 8 is rotated, and the normally used locking surface 8b with a radial length B is replaced with a locking surface 8c with a radial length C longer than B. It will lock properly. If the gap is still not absorbed, the adjuster 8 may be further rotated to lock the locking surface 8d instead of the locking surface 8d having a length D longer than C in the radial direction. In addition, in the case of S3 where the distance between the lock lever 4 and the hook 6 is long, the position of the hook 6 is higher than usual, and the tip of the hook 6 is bent into a U shape, so the locking surface that is normally used is 8b in the direction of arrow B in Fig. 2 to lock the lock itself, the tip of the hook 6 gets in the way and cannot be locked, but by rotating the adjuster 8, the locking surface that is normally used If the locking surface 8a is replaced with the locking surface 8a having a shorter radial length than the locking surface 8b, the locking surface can be properly locked. Further, in this embodiment, since the latch 7 is fixed by the fixing grooves 9 provided at both ends of the adjuster 8, it is possible to stop the adjuster from rotating.
In this embodiment, the adjuster 8 is a rectangular parallelepiped, but it may be made into a hexagonal prism or the like to widen the adjustment range.

(Effects of the invention) As explained above, according to the invention, a latch is provided between the lock lever connected to the base plate attached to the floor panel and the hook provided on the seat cushion. By providing an adjuster on the side of the latch that connects to the hook, it is possible to correct dimensional errors in the distance between the lock lever and the hook during assembly.
