Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a seat slide mounting structure applied when a seat is installed on a vehicle body side.

[Prior Art] A seat installed in a vehicle has a seat slide device attached to a lower surface side of the seat, and a portion of the seat slide device, for example, front and rear ends of a lower rail 101 constituting the seat slide device as shown in FIG. The portion is arranged on the vehicle body side with a cushioning rubber 102 interposed, and is fixed to the vehicle body side using bolts 103.

As a result, even if the vehicle body vibrates, this vibration is absorbed by the cushioning rubber 102 and is not directly transmitted to the seat, thereby improving the sitting comfort when seated.

[Problems to be Solved by the Invention] However, with such a seat slide mounting structure, although the vertical vibration of the vehicle body can be absorbed to some extent as shown in FIG. 5, the longitudinal vibration and lateral vibration of the vehicle body are effective. Therefore, there is a problem that the ride comfort is not good when the vehicle body vibrates back and forth or left and right.

In view of the above-mentioned circumstances, the present invention can absorb the vibration not only when the vehicle body vibrates up and down but also when the vehicle body vibrates back and forth and left and right to ensure a comfortable sitting comfort. It is intended to provide a mounting structure for a slide.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a seat slide mounting structure in which a seat slide device provided on a lower surface of a seat is fixedly held on a vehicle body side using a mounting bracket. The bracket is a lower angle fixed to the vehicle body side,
An upper angle that is fixed on the lower angle and has an upper opening, a leaf spring that is fixed in a erected state between support portions that integrally project from both inner side walls of the upper angle, and that is provided at a substantially central portion of the leaf spring. And a locking portion for stopping a connecting bolt projected from a corresponding end portion of the seat slide device, and the brackets are respectively interposed between front and rear end portions of the seat slide device and the vehicle body side. Is the main part.

[Operation] According to the above configuration, when the vehicle body vertically vibrates, longitudinally vibrates, or laterally vibrates, the leaf springs fixed on the inner walls of the upper angle and fixed between the supporting portions absorb the vibrations. And keep the seat slide vibration free.

[Embodiment] FIG. 1 is an exploded perspective view showing an embodiment of a seat slide mounting structure according to the present invention.

In the seat slide mounting structure shown in this figure, a mounting bracket 3 is interposed between the front and rear ends of a lower rail 2 that constitutes the seat slide device 1 and the vehicle body side. A seat (not shown) that is placed is fixed to the vehicle body side.

The bracket 3 has a lower angle 6 formed in a substantially inverted L-shape having a vehicle body mounting hole 5 and a substantially angled U-shaped cross section that is welded and fixed (or fixed by another method) to the upper horizontal portion of the lower angle 6. It is provided with an upper angle 7, a supporting portion 8 projecting from an inner wall facing the upper angle 7, and an intermediate assembly 9 fixed between the supporting portions 8 in a erected state.

The intermediate assembly 9 includes a leaf spring 10 which is bendable between the support portions 8 and whose position is regulated by a not-shown cut-and-raised portion formed at an end portion of each support portion 8 (this leaf spring is for cushioning. , Also referred to as a spring body), a plate-like mounting plate 11 fixed to a substantially central portion of the upper surface of the plate spring 10, and a plate spring 10.
And a nut 12 as a locking portion fixed to the lower surface of the.

Further, in the mounting plate 11 and the leaf spring 10, a hole 14 slightly larger than the screw hole 13 is formed in a portion corresponding to the screw hole 13 of the nut 12.

As shown in FIG. 2, the above intermediate assembly 9 has the upper angle 7
When it is incorporated in the supporting portion 8, the side end portion of the leaf spring 10 is fixed to the corresponding supporting portion 8 by welding, or a cut-and-raised portion is provided from the supporting portion 8 so that the position can be regulated.

The nut 12 as a locking portion can be fixed to the upper surface of the mounting plate 11 or the hole 14 itself can be omitted by forming a female screw structure.

When mounting the seat on the vehicle body side, after the upper surface side of the mounting plate 11 constituting the bracket 3 is brought into contact with the lower surface side of the lower rail 2 of the seat slide device 1 mounted on the lower surface of the seat, the lower rail 2 Align the hole 15 provided at the end with the hole 14 of the mounting plate 11, insert a bolt 16 from the hole 15 side, and tighten it to tighten the bolt 16
These are integrated with the nut 12.

Next, the bracket 3 is placed on the floor of the vehicle body, and the vehicle body mounting bolt 4 is inserted into the mounting hole 5 of the lower angle 6 that constitutes the bracket 3 and tightened to fix the bracket 3 to the vehicle body side. Completed fixing to the vehicle body.

As described above, in this embodiment, the front and rear ends of the seat slide device 1 are fixed to the vehicle body side through the brackets 3. Therefore, when the vehicle body vibrates up and down as shown in FIG. Of course, the intermediate assembly 9 of the bracket 3 is configured when the vehicle body oscillates back and forth or sways, or when the vehicle body sways in the lateral direction as shown in FIG. 3 (b). The leaf spring 10 which is absorbing absorbs the vibration on the vehicle body side. With this, it is possible to prevent the vibration from being transmitted to the seat, and it is possible to secure a comfortable sitting comfort.

Although the upper and lower angles 7 and 6 are separate bodies in the embodiment,
Both angles 7 and 6 may be integrated.

[Effect of the Invention] As described above, according to the present invention, the leaf spring is fixed in a erected state between the supporting portions protruding on the inner wall of the upper angle, and the seat slide is attached to the locking portion provided on the leaf spring. Since the bolt protruding from the device side is locked, it is possible to efficiently absorb this vibration not only when the vehicle body vibrates up and down but also when the vehicle body vibrates back and forth and left and right. A comfortable sitting comfort can be secured.
