Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a sliding device for a knuckle type automobile seat on both sides.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 3, an automobile seat is composed of a seat cushion 1 and a seat back 2, and both side portions of the seat cushion 1 and the seat back 2 are knuckles (not specifically shown). Connected (Knuckle type on both sides). A buckle 4 that locks the tongue plate of the seat belt 3 is provided on the seat cushion 1.

On the other hand, as shown in FIG. 2, the slide device has a lower channel 5 fixed to the vehicle body floor and an upper channel 6 fixed to the seat cushion 1. In addition, 7 is a ball and 8 is a roller for smoothing the slide of both channels 5 and 6.

The side frame 9 of the seat cushion 1 is fixed to the upper part of the upper channel 6, the lower knuckle 10 is arranged outside the side frame 9, and the cushion frame 11 is arranged inside thereof. , The side frame 9 and the cushion frame 11 are fixed together by the first bolt and nut 12. A first hook 14 facing upward is fixed to an outer portion of the upper channel 6, and a second hook 13 that extends outwardly from the lower portion of the lower channel 5 and engages with the first hook 14 from above. Is fixed. The hooks 13 and 14 are for locking the upper channel 6 so as not to come off from the lower channel 5 when a large load is applied to the upper channel 6. The bracket 15 of the buckle 4 is fixed by a second bolt / nut 17 to the rising portion 14a that largely rises upward from the first hook 14.

[0005]

[Problems to be solved by the device]

 However, in the above-described slide device, the seat belt buckle 4 and the hooks 13 and 14 project outside the side frame 9 with the width W, so that the seat width increases by the width W which is ineffective as a seating portion. was there. Further, since the first hook 14 needs a large rising portion 14a, there is a problem that the weight of the seat increases. Further, since two sets of bolts and nuts 12 and 17 are required, there is a problem that the assembling property is poor.

Therefore, an object of the present invention is to provide a two-sided knuckle type vehicle seat sliding device capable of effectively increasing the seat width as a seating portion, reducing the weight of the seat, and assembling easily. Especially.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention includes a seat cushion and a seat back, both sides of which are connected by knuckles, and a lower channel fixed to a vehicle body floor and an upper channel fixed to the seat cushion. In a sliding device for an automobile seat having, a first hook that faces upward is fixed to an inner portion of the upper channel, and a second hook that extends inwardly and engages with the first hook from above is attached to a lower portion of the lower channel. While the hook is fixed, the side frame of the seat cushion is fixed to the upper part of the upper channel, the lower knuckle is arranged outside the side frame, and the cushion frame and the seat belt buckle bracket are arranged inside. , The lower knuckle, side frame, cushion frame and boot Packet is characterized by being fastened together with bolts and nuts.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail with reference to illustrated embodiments. As shown in FIG. 1, in a two-sided knuckle type automobile seat, a first hook 21 facing upward is fixed to an inner portion of an upper channel 20. The first hook 21 is not provided with a rising portion (see the same 14a) as the conventional first hook (see the reference numeral 14 in FIG. 2). A second hook 23, which extends inward and engages with the first hook 21 from above, is fixed to the lower portion of the lower channel 22. The first and second hooks 21 and 23 are located inside the conventional first and second hooks (see 14 and 13), while they are located inside the channels 20 and 22. The difference is that. Incidentally, 30 is a ball and 31 is a roller.

A side frame 24 of the seat cushion 1 (see FIG. 3) is fixed to the upper portion of the upper channel 20, and a lower knuckle 25 is arranged outside the side frame 24. Inside the side frame 24, a cushion frame 26 and a bracket 28 of a seat belt buckle 27 are arranged.

The lower knuckle 25, the side frame 24, the cushion frame 26, and the bracket 28 are fixed together by a set of bolts and nuts 29.

According to the above configuration, the bracket 28 of the seat belt buckle 27 is located inside the side frame 24, and the hooks 21 and 23 are also located inside the channels 20 and 22, respectively. It does not project to the outside of the frame 24. Therefore, if the seat width is increased by the width W in FIG. 2, it is effective as a seating portion, so that the seating property and the feeling of volume are improved. Further, since the mounting width of each of the left and right channels 20 and 22 is simply widened, the strength of the seat cushion does not decrease even if the seat width increases.

Further, since it is not necessary to provide the first hook 21 with a large rising portion (see 14a in FIG. 2) unlike the conventional first hook (see reference numeral 14 in FIG. 2), the weight of the seat is reduced. .

Further, since the bracket 28 of the lower knuckle 25, the cushion frame 26 and the buckle 27 can be fixed to the side frame 24 with only one set of bolts and nuts 29, the number of parts can be reduced and the assembling can be reduced. The property is also improved.

[0014]

[Effect of device]

 As is clear from the above description, in the sliding device for a vehicle seat of the knuckle type on both sides of the present invention, the bracket of the seatbelt buckle is located inside the side frame, and the first and second hooks are also provided. Since it is located inside the channel, it does not project outside the side frame. Therefore, if the seat width is made the same as the conventional width, the seating portion is enlarged, and the seating comfort and the feeling of volume are improved. Further, since it is not necessary to provide a rising portion on the first hook, the weight of the seat is reduced. Furthermore, the lower knuckle, cushion frame, and buckle can be fastened together to the side frame with only one set of bolts and nuts, which improves the ease of assembly.
