Problems solved by technology

However, reducing the size of the adjustable angle device will reduce the contact strength between the gear and the tooth gap, causing the adjustable angle device to stop working, and the seat will also swing back and forth, which may also cause the seat back to fail, threatening the safety of passengers

Embodiment Construction

[0016] The present invention will be described in detail along with the drawings.

[0017] figure 1 and figure 2 is a perspective view of the angle-adjustable device of the present invention. According to the first embodiment, Figure 1 to Figure 7 First, an angle-adjustable device connected to a power transmission device will be described. As shown in the figure, the adjustable angle device of the present invention has a wheel shaft 1, an external gear support 10, an internal gear support 20, a sleeve block 30, a bearing 40, a power transmission device, a cover plate 50 and A guide bracket 60 .

[0018] The external gear bracket 10 is a ring-shaped element, which is connected to the seat back device by a fixing element. The external gear bracket 10 has a central hole 11 at the center, and an internal gear type external gear 12 has a plurality of teeth and is along the circumferential edge. continuous setting.

[0019] The internal gear support 20 is an annular element,...

Abstract

The present invention relates to a reclining device of a seat for a vehicle, which makes it possible to prevent backlash between an external gear 12 and an internal gear 22 in stop, resulting in preventing a vibration noise due to movement of the seatback. Further, it is possible to obtain sufficient power from even a small-output motor in operation, by minimizing the gear press angle to increase the operational efficiency. In addition, it is possible to design a compact reclining device by simplifying the shape and reduce the size of assemblies of wedge blocks 70, 120 and cams 80, 110, resulting in reducing the weight and the manufacturing cost and making it possible to freely designing the reclining device, depending on a disposing space.

Description

technical field [0001] The invention relates to an angle-adjustable device, in particular to an angle-adjustable device for a vehicle seat. Background technique [0002] Generally speaking, a vehicle seat is supported by a seat back and a seat cushion to support a passenger's back, buttocks and thighs, wherein the angle of the seat can be adjusted by an angle-adjustable device. In addition, the angle-adjustable device has two left and right recliners, which are placed on the left and right sides of the seat, and the end of the connecting shaft is connected to the left and right recliners through a rack. The connecting shaft is rotated by an electric motor as power transmission. On the other hand, since the angle-adjustable device is connected to the seat back and the seat cushion, it is better to reduce the size and thickness of the angle-adjustable device. However, reducing the size of the adjustable angle device will reduce the contact strength between the gear and the t...
