Detailed Description

In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

In order to facilitate the technical solution disclosed by the present invention to be fully understood by those skilled in the art, fig. 1 shows a schematic perspective view of a first embodiment of the middle automobile seat basin angle adjustment guide of the present invention, which is known to include an integrated injection molded guide body 1. The guide body 1 includes a through cavity 11, a first coupling portion 12, a connecting arm 13, a second coupling portion 14, and a support arm 15. The through cavity 11 is for the tilt adjusting member to pass through, is semi-open, and is formed by the first coupling portion 12, the connecting arm 13, the second coupling portion 14, and the supporting arm 15 in sequence and surrounding clockwise. The support arm 15 is formed by extending the second coupling portion 14 rightward and extends into the interior of the above-mentioned through cavity 11 (as shown in fig. 2). It should be emphasized that the angle-adjusting guide 1 further includes an elastic pressing arm 16, which is formed by extending the sidewall of the second coupling portion 14 toward the through cavity 11 and is disposed right below the supporting arm 15 to cooperate with the supporting arm 15 to elastically press the tilt adjusting member, and accordingly, a receiving groove 131 (as shown in fig. 2) is formed on the connecting arm 13, in which the shape of the elastic pressing arm 16 is adapted to the shape of the tilt adjusting member. In this way, even if the seat pan is abraded during the adjustment process of the inclination angle of the seat pan, the elastic pressing arm 16 can reliably press the inclination adjusting member under the action of the elastic restoring force, so that a good contact state is always kept between the inclination adjusting member and the seat pan angle adjusting guide member, and the stable seat pan angle adjustment process is further ensured.

As a further optimization of the structure of the seat pan angle adjustment guide of the automobile seat, the wall thickness of the connecting arm 13 is assumed to be h1, the width thereof is w1, the wall thickness of the elastic pressing arm 16 is assumed to be h2, and the width thereof is w2, then h2 is not less than 1/2h1, and w2 is not less than 1/2w1 (as shown in fig. 4 and 5), so that, on one hand, the elastic restoring force of the elastic pressing arm 16 per se is effectively ensured, and the reliable pressing of the side wall of the tilt adjustment member is ensured; on the other hand, the difficulty of injection molding of the elastic pressing arm is effectively reduced, and the molding quality of the elastic pressing arm is ensured.

Furthermore, it is also possible to provide the support arm 15 and the resilient pressure arm 16 with a wear-resistant coating (not shown in the figures) on the side directly corresponding to the tilt adjustment member. The presence of the wear-resistant coating reduces to some extent the relative rate of wear of the tilt adjustment member to the support arm 15 and the resilient pressing arm 16, effectively ensuring that the tilt adjustment member is reliably pressed for a long period of time.

For the convenience of the tilting adjustment member entering the through cavity 11 and for avoiding the occurrence of the jamming phenomenon in the subsequent practical application, a guiding inclined plane 151 may be further provided at the free end of the supporting arm 15, and correspondingly, a transition arc surface 111 (as shown in fig. 4) may be provided at the inlet area of the through cavity 11.

As a further refinement of the structure of the guiding element body, a first countersunk bolt hole 121 may be further formed in the first coupling portion 12, and a second countersunk bolt hole 141 (as shown in fig. 3) may be further formed in the second coupling portion 14, so that the coupling bolt passes through the first countersunk bolt hole and the second countersunk bolt hole, and the fixing with the seat frame is further achieved, thereby effectively ensuring the fixing reliability of the automobile seat basin angle adjusting guiding element, and the dismounting process is fast and convenient for the execution of the later maintenance work.

Of course, in order to improve the positioning accuracy of the car seat pan angle adjustment guide itself, a limit pin hole 142 (as shown in fig. 3) may be further formed on the second coupling portion 14. The stopper pin holes 142, the number of which is at least 2, are arranged on one side of the second countersunk bolt hole 141 and are evenly distributed along the width direction (i.e., the front-rear direction in fig. 1) of the second coupling part 14.

Fig. 6 is a schematic structural diagram of a second embodiment of the guiding member for adjusting the seat pan angle of the car seat of the present invention, which is different from the first embodiment of the above-mentioned guiding member: a spacer 2 is additionally provided. A limit step 132 is extended along the inner side wall of the receiving recess 131 and is disposed just below the free end of the elastic pressing arm 16. The adjusting shim 2 is placed on and fixed on the upper plane of the limiting step 132, so that the restoring force of the elastic pressing arm 16 can be adjusted conveniently by increasing or decreasing the thickness of the adjusting shim 2, and the stability of the adjusting process of the inclination angle of the seat basin is further ensured.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
