Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device that facilitates the installation and removal of a vehicle seat.

BACKGROUND OF THE INVENTION Vehicle seats, particularly rear seats, are sometimes temporarily removed and the cover replaced. Therefore, in the conventional vehicle, as shown in FIGS. 4 and 5, the rear seat wire 5 is initially made to protrude in a U-shape from the lower end of the rear seat 51.
3 is a hole 54 provided in the sheet mounting table 52 on the floor.
and was secured with bolt 55. However, this attachment means has the disadvantage that when removing the seat 51, the bolts 55 must be removed in a narrow space inside the vehicle, which is time consuming.

Therefore, as an improvement to the above-mentioned attachment means, the sixth
As shown in the figure, a device using a lock spring 61 has been proposed. This lock spring 6
1 is a lever 62 equipped with a knob 63 and a locking part 6
4. Holding part 6 fixed to rear seat wire 53
6, a hook part 67.

When attaching the rear seat 51, the lower end of the rear seat wire 53 is held by the holding portion 66 and inserted into the insertion hole 70 of the seat mounting base 52 on the floor. In the fully inserted state, the locking portion 64 of the lock spring 61 enters the insertion hole 70 and then expands due to its elastic force, comes into contact with the inner surface 71 of the insertion hole 70, and is prevented from coming off. The hook portion 67 is hooked on the upper surface 72 of the insertion hole 70.

When removing the rear seat 51 attached in this way, pull the knob 63 of the lever 62 in the direction of the arrow in the figure, and the locking part 64 will be released from the inner surface 71.
The rear seat 51 can be lifted and removed.

Problems to be Solved by the Invention The mounting device using the lock spring 61 described above is easy to operate, but it requires a large hole 70 to be provided on the seat platform 52 on the floor, and a back plate 73 cannot be attached. However, there was still a drawback that water leaked from the hole 70.

Means for Solving the Problems In order to solve the above-mentioned drawbacks of the conventional mounting device, the present invention provides a spring piece that expands inside the hole of the seat mounting base on the floor, and a holding part that locks on the seat wire. and a lock spring provided with a lever for operating the spring piece; an insertion hole into which the lock spring is inserted, an insertion hole through which the spring piece can be inserted and expanded; Provided is a vehicle seat mounting device, characterized in that the device is combined with a grommet having an elastically deformable collar portion on the entire periphery so as to cover the entire hole and an umbrella portion having a groove into which the lever fits. It is something to do.

Effect By configuring the present invention as described above,
A sheet wire is locked to the holding part of the lock spring, and the sheet wire is inserted through the insertion hole of the grommet, and the locking part of the lock spring is expanded through the insertion hole of the grommet. When the seat set in this manner is inserted into the hole in the seat table on the floor through the grommet, the lock spring expands inside the hole and performs a locking action. At this time, the brim of the grommet elastically adheres to the entire periphery of the hole to cover the entire hole, preventing water from leaking from the hole, and the lever fitting into the groove prevents the lever from wobbling.

When removing the seat, when the lever is pulled, the locking portion is retracted from inside the hole, allowing the entire seat to be lifted and removed.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 3.

FIG. 1 shows a state in which the seat mounting device of the present invention is incorporated and a seat 1 is attached. As shown in FIG. 2, most of the structure of the lock spring 11 is the same as the conventional one described above. That is, the lock spring 11 includes a lever 12 with a knob 13, a locking part 14, a holding part 16 fixed to the rear seat wire 3, and a hook part 1.
7. First spring piece 15 between locking part 14 and holding part 16, second spring piece 1 with hook part 17
8, and an abutment piece 19 between the lever 12 and the locking portion.

On the other hand, the grommet 31 is made of an elastic piece, and is composed of an upper umbrella part 32 and a lower insertion part 34. The umbrella part 32 has a collar part 33 around the entire periphery, and an insertion hole 36 for the first spring piece 15 is provided on one side of the insertion part 34 . The grommet 31 has an insertion hole 35 passing through it in the vertical direction, and the lever 12 of the lock spring 11 is placed on the umbrella portion 32 of the insertion hole 35.
A groove 37 is provided in which the groove 37 fits.

In the above configuration, when the rear seat 1 is installed, the holding portion 16 of the lock spring 11 is engaged with the lower end of the rear seat wire 3 to hold it therein. Next, when the lock spring 11 attached to the rear seat wire 3 is inserted into the insertion hole 35 of the grommet 31 from above, the first spring piece 15 and the second spring piece 18 are inserted while being compressed, and the locking part 14 is inserted into the insertion hole 36. When the upper end is exceeded, the locking portion 14 will pop out from the insertion hole 36 due to the spring action. At that time, the contact piece 19 is attached to the inner surface 38 of the insertion hole 35.
, and the second spring piece 18 fits into the groove 39 provided on the inner surface of the insertion hole 35 together with the hook portion 17 . The lever 12 also fits into the groove 37.

When the seat mounting device set in this manner is inserted into the hole 41 provided in the sheet mounting table 2 on the floor, the first spring piece 15 is inserted while being compressed at the periphery of the hole 41, and the locking portion 14 is inserted into the hole 41. When it penetrates, it opens due to its spring force and sheet 1
is fixed to the floor. At this time, grommet 31
The umbrella part 32 is pressed by the sheet 1, and the collar part 3
3 is in close contact with the upper surface of the sheet mounting table 2 on the floor. This close contact provides a sealing effect on the periphery of the hole 41.

To remove the seat 1 attached in this manner, pull the knob 13 provided on the lever 12 until the contact piece 19 contacts the other side of the inner surface 38 of the insertion hole 35. The locking piece 14 is then pulled into the hole 41, and can be removed by lifting the entire sheet 1.

Effects of the invention This invention is constructed and operates as described above, so
Not only is it extremely easy to install and remove the seat, but the grommets on the outer periphery of the lock spring, especially the brim, prevent water dripping and dust from entering through the holes in the seat platform on the floor. can.

Due to the improved sealing effect, it becomes possible to drill holes in the floor, improving the degree of freedom in arranging the mounting portion.
