Description

[Detailed description of the invention] "Field of industrial application" This invention consists of a rail on the seat side that is attached to the seat panel side and a rail on the vehicle body side that is movably fitted to the rail on the seat side. The present invention relates to a seat slide device having a unit.

"Conventional technology" Conventional seat slide devices include, for example,
There is one disclosed in Japanese Utility Model Application Publication No. 51-25324.

In other words, the rail on the car body side is movably fitted into the rail on the seat side, and the rail on the seat side has a substantially horizontal main surface plate that extends largely to both sides, and the separation between the rail on the seat side and the rail on the car body side. In order to prevent this, it has a holding flange that fits outward so as to wrap around the almost horizontal fitting flange of the rail on the vehicle body side, and also has a holding flange that fits around the almost horizontal fitting flange of the rail on the side of the seat. The members are fixed and configured to be able to engage with the engaging member of the rail on the vehicle body side.

``Problems to be solved by the invention'' However, in such conventional seat slide devices, an engaging member is purposely provided to improve the peeling strength between the rail on the seat side and the rail on the vehicle body side. This increases the number of points, which increases costs.Also, since the main surface plate of the seat side rail protrudes greatly to both sides, if you try to widen the side wall of the seat panel sufficiently, the side wall of the seat panel will overlap the main surface plate. For example, if the rail unit and seat panel are moved relative to each other in the vertical direction to avoid interference, the seat panel may be installed at a higher position, resulting in poor space efficiency. There was a problem.

The present invention was created by focusing on the problems of the conventional technology, and aims to improve the efficiency of installation space and improve peel strength without increasing cost with a simple configuration. The purpose of the present invention is to provide a seat sliding device that can perform the following functions.

``Means for Solving the Problems'' The gist of the present invention for achieving the above purpose is as follows: A rail on the vehicle body side, and a seat side that movably fits into the rail on the vehicle body side and supports the seat. In a seat slide device having a rail unit consisting of a rail, in which a bracket for fixing to the vehicle body side is fixed to the rail on the vehicle body side, the cross section of the rail on the seat side is defined by one side being a substantially horizontal base. The other two sides are formed into a substantially triangular shape with at least the side facing the seat panel as the hypotenuse, and the rail on the vehicle body side is formed in a substantially triangular cross section like the rail on the seat side. and the vehicle body side fixing bracket is fitted and fixed to the front end and rear end of the rail on the vehicle body side along the three sides of the substantially triangular cross section. The seat slide device consists of

"Function" When the rail on the car body side is movably fitted onto the rail on the seat side, if a peeling load is applied between the rail on the car body side and the rail on the seat side, the parts other than the base of each approximately triangular cross section will The two sides touch each other and try to open the two sides of the rail on the car body side.

Since the vehicle body side fixing bracket is fitted along the three sides of the roughly triangular cross section of the vehicle body side rail, it prevents the two sides of the vehicle body side rail from opening, and therefore the vehicle body The side rail and the seat side rail do not separate from each other.

When the rail on the seat side is movably fitted onto the rail on the car body side, if a peeling load is applied between the rail on the car body side and the rail on the seat side, the bottom sides of each approximately triangular cross section will come into contact with each other. and try to pull up the rail on the vehicle body side.

Since the bracket for fixing on the vehicle body side is fitted along the three sides of the roughly triangular cross section of the rail on the vehicle body side, the bracket for fixing on the vehicle body side will resist the force that tries to pull up the rail on the vehicle body side. Therefore, the rail on the vehicle body side and the rail on the seat side will not separate from each other.

In addition, if the side wall of the seat panel is formed close to the oblique side of the rail on the seat side, the width of the side wall of the seat panel can be sufficiently increased, and even when the rail unit is attached to the seat panel, The installation position of the seat panel does not become unnecessarily high by shifting the seat panel upward from the rail unit, for example, and the efficiency of the installation space can be improved.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

1 to 7 show an embodiment of the present invention.

As shown in FIG. 3, a seat cushion 30 that tiltably supports the seat back 20 is attached to the vehicle floor 10 via a pair of rail units 40a, 40a arranged with the longitudinal direction facing forward and backward. There is.

As shown in FIG. 7, the cross section of the seat panel 32 of the seat cushion 30 is formed from a substantially horizontal bottom plate portion to a substantially vertical side wall 38 via an inclined surface 36. This serves as a mounting surface for the rail unit 40a.

As shown in Figures 1 and 4 to 7,
The rail unit 40a is constructed by fitting a seat-side rail 50 into a vehicle body-side rail 40 so as to be movable back and forth.

The rail 40 on the vehicle body side is formed to have a substantially triangular cross section, with one side being a substantially horizontal base, the side facing the seat panel side being an oblique side, and the other side being a vertical side.

Similarly, the rail 50 on the seat side has a substantially right triangular cross section, with one side being a substantially horizontal base, the side facing the seat panel side being an oblique side, and the other side being a vertical side. , each side is fitted with a corresponding side on the rail 40 side of the vehicle body with a certain gap between them.

In the rail 40 on the vehicle body side, an inclined face plate 41 corresponding to an oblique side and a vertical face plate 42 corresponding to a vertical side are placed close to each other at a predetermined distance apart at the upper part, and further extended in the vertical direction while being separated by a predetermined distance. These are extended portions 44 and 45, respectively. Extension part 44,
45 are fixed to each other by a caulking pin 48 at a predetermined distance apart.

Similarly, in the rail 50 on the seat side, an inclined face plate 51 corresponding to the oblique side and a vertical face plate 52 corresponding to the vertical side almost overlap at the upper part, and in the overlapping state, they are further extended in the vertical direction to extend respectively. Sections 54 and 55. Extension part 54,5
5 are spot welded to each other at predetermined locations.

As shown in FIGS. 1 and 5, the inclined surface plate 4
A hemispherical recess 41a is formed in the inclined surface plate 51, and a guide groove 51a having a hemispherical cross section and extending in the longitudinal direction is formed in opposition to the hemispherical recess 41a.
A spherical bearing 60 is rotatably disposed in contact with the hemispherical recess 41a and the guide groove 51a.

Similarly, the vertical face plate 42 has a hemispherical recess 4.
2a is formed, and a guide groove 52a having a hemispherical cross section and extending in the longitudinal direction is formed in the vertical face plate 52 in opposition to the hemispherical recess 42a, and the guide groove 52a is in contact with the hemispherical recess 42a and the guide groove 52a. A spherical bearing 60 is arranged to be able to roll.

Further, a substantially semi-cylindrical recess 53a is formed in the bottom plate 53 corresponding to the bottom side of the rail 50 on the seat side, and the substantially semi-cylindrical recess 53a and the rail 50 on the vehicle body side
A cylindrical bearing 65 is rotatably disposed in contact with the bottom plate 43 corresponding to the bottom side of the 0 side.

The extension parts 44 and 45 are formed with lock parts 47 and 47 which are opposed to each other and have a large number of engagement protrusions 46 connected in the longitudinal direction. The member 57 is the extension part 5
4 and 55 so as to be swingable.

As can be seen in FIGS. 1 and 7, the extension portion 5
4 and 55 are spaced apart from each other by a predetermined distance at the rear end, and the frame 22 of the seat bag 20 is pivotally connected to the seat bag 20 by a pivot shaft 25 while being sandwiched between the extending portions 54 and 55 that are spaced apart from each other.

As shown in FIGS. 1 and 4, the front end of the rail 40 on the vehicle body side is fitted with an inclined surface plate 41, a vertical surface plate 42, and a bottom surface plate 43 from the outside for fixing to the vehicle body side. A bracket 71 is fixed by a caulking pin 75.

Similarly, as shown in FIGS. 1 and 6, the rear end of the rail 40 on the vehicle body side is fitted with an inclined surface plate 41, a vertical surface plate 42, and a bottom surface plate 43 from the outside. A bracket 72 for fixing to the vehicle body side is fastened with bolts 76. bolt 7
6, the belt anchor 39 is also tightened together.

Next, the effect will be explained.

When a peeling load is applied between the rail 40 on the vehicle body side and the rail 50 on the seat side, the inclined surface plate 51 comes into contact with the inclined surface plate 41, and the vertical face plate 52 contacts the vertical face plate 42 back and forth. Inclined surface plate 51 and vertical surface plate 52
attempts to open the inclined surface plate 41 and the vertical surface plate 42.

Due to the rigidity of the rail 40 itself on the vehicle body side and the caulking pin 48, the slope plate 41
This prevents the vertical face plate 42 from opening, so that the rail 40 on the vehicle body side and the rail 50 on the seat side do not separate.

Furthermore, the inclined surface plate 41 and the vertical surface plate 42 are connected to a caulking pin 75 and a bracket 7 for fixing to the vehicle body side.
1, as well as the rigidity of the bolt 76 and the bracket 72 for fixing to the vehicle body side, the opening is prevented.

Thereby, even if an excessive peeling load is applied, the rail 40 on the vehicle body side and the rail 50 on the seat side will not separate.

When assembling the seat panel 32 and the rail unit 40a, the inclined surface 36 of the seat panel 32 is formed along the inclined surface plate 51 of the rail 50 on the seat side, and the substantially vertical side wall 38 is formed along the extending portion 54. If the seat panel 3 is formed along the
The lateral width of 2 can be widened sufficiently.

If the seat panel 32 and the rail unit 40a formed in this way are attached, they will not interfere with each other, and therefore there is no need to, for example, shift the seat panel 32 upward from the rail unit 40a. Improves space efficiency.

According to the seat slide device according to the above embodiment, the rail 40 on the vehicle body side is movably fitted onto the rail 50 on the seat side, but conversely, the rail on the seat side is fitted externally onto the rail on the vehicle body side. It may be something you have done. In that case, for example, a bracket for fixing to the vehicle body side may be fitted along the inner surface of each face plate of the rail on the vehicle body side.

"Effect of the invention" According to the seat slide device according to the invention, since the part of the rail on the side of the vehicle body facing the seat panel is inclined, both sides of the seat panel are fully aligned with the rail on the side of the vehicle body. They can be mounted close together, there is no need to move the seat panel upwards, and the efficiency of installation space can be improved.
In addition, the rail on the vehicle body side and the rail on the seat side are fitted to each other so that one almost completely surrounds the other, and the rail on the vehicle body side and the bracket for fixing the vehicle body side are also fitted together so that one side almost completely surrounds the other. Since the two parts are fitted and fixed to each other so as to almost completely surround the other part, the peel strength can be improved without increasing the number of types of parts and without increasing costs.
