Description

Technical Field

[0001] This utility model relates to a zero-gravity seat with a seatbelt that can be pulled up or down at will. Background Technology

[0002] Patent CN216684375U discloses a zero-gravity car seat that allows for arbitrary retraction and extension of the seat belt. The seat belt includes a backrest assembly, a seat cushion assembly, and a base assembly. The backrest assembly is hinged to the rear end of the seat cushion assembly via an angle adjuster. The seat cushion assembly includes two seat frame side plates arranged opposite each other and a rear cross tube fixedly connected between the two seat frame side plates. A retractor is provided below the seat cushion assembly and is fixed to the base assembly via a retractor mounting bracket. A pull-out opening is provided at the upper end of the backrest assembly. Seat belt guide brackets are provided on the backrest assembly, seat cushion assembly, and base assembly to allow the seat belt in the retractor to pass backward around the rear cross tube and then extend upward to the pull-out opening. The aforementioned car seat has a seatbelt guide bracket that is only a pivot. During the retraction and extension process, the seatbelt will sag to a certain extent, and the seatbelt is prone to coming off the bracket. If a traditional slotted bracket is used, once the seatbelt twists during use, it will get stuck on the bracket and cannot be pulled out or retracted. Moreover, since these brackets are enclosed inside the seat, maintenance is also very difficult. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a zero-gravity seat with a seat belt that can be pulled up and down at will. The seat belt guide bracket has been improved so that the seat belt is not easy to come off the bracket or get stuck on the bracket.

[0004] The technical solution of this utility model is: a zero-gravity seat with a seat belt that can be arbitrarily pulled and retracted, including a seat belt guide bracket set on the seat. The seat belt guide bracket includes a connecting seat for fixing to the seat, two guide plates set on both sides of the connecting seat for guiding, a first guide wheel that is slidably connected between the two guide plates, and a second guide wheel set below the first guide wheel. Both the first guide wheel and the second guide wheel are V-shaped wheels; The first guide wheel and the second guide wheel extend out of the outer sides of the two guide plates at both ends, and elastic cables are connected between the two ends of the first guide wheel and the second guide wheel. The first guide wheel and the second guide wheel tend to abut against each other under the action of the elastic cables, and the gap between the first guide wheel and the second guide wheel forms a hole for the seat belt to pass through.

[0005] Furthermore, the front end of the connecting seat is provided with two support columns, and the two guide plates are respectively welded to the connecting seat and the two support columns. The connecting seat and the two support columns are integrally formed structures.

[0006] Furthermore, each of the two guide plates is provided with a guide groove, and the outer ends of the two guide grooves are respectively located behind the inner side of the two support columns.

[0007] Specifically, the two guide plates are arranged vertically or inclined to the connecting seat.

[0008] Furthermore, both the first guide wheel and the second guide wheel include an axle and a wheel body. The wheel body is rotatably connected to the axle. Two guide grooves extend from both ends of the axle of the first guide wheel. The axle of the second guide wheel is rotatably connected to two guide plates. Both the first guide wheel and the second guide wheel can rotate on their own.

[0009] Furthermore, limit caps are fixed to both ends of the axles of the first guide wheel and the second guide wheel, and the limit caps are provided with grooves corresponding to the elastic cables.

[0010] Furthermore, the seat consists of a backrest assembly, a seat cushion assembly, and a connecting seat assembly, with the seat belt retractor fixed to the connecting seat assembly.

[0011] Furthermore, there are three seat belt guide brackets, which are named the first bracket, the second bracket, and the third bracket, respectively. The first bracket is fixed upside down on the connecting seat, and the second and third brackets are fixed on the seat cushion assembly and the backrest assembly, respectively.

[0012] Furthermore, the connecting seat is provided with fixing holes, and the connecting seat is fixed to the seat by fixing bolts.

[0013] The beneficial effects of this utility model are as follows: In this utility model, the seat belt passes between the first guide wheel and the second guide wheel on the seat belt guide bracket. At this time, the seat belt is limited by the two guide plates, the first guide wheel and the second guide wheel, and is not easy to fall out of the guide bracket. Since the first guide wheel and the second guide wheel are both V-shaped wheels, the seat belt is not easy to fall out of the groove of the first guide wheel or the second guide wheel and get stuck in the gap between the guide wheel and the guide plate when the seat belt is pulled. Since the first guide wheel can slide up and down, and the two ends of the first guide wheel and the second guide wheel are connected by an elastic cable, even if the seat belt is twisted, it can smoothly push open the first guide wheel and the second guide wheel, avoiding the seat belt from getting stuck and unable to be pulled, thereby achieving smooth pulling and retracting of the seat belt.

The first guide wheel 3 and the second guide wheel 4 are both V-shaped wheels; The first guide wheel 3 and the second guide wheel 4 extend out of the outer sides of the two guide plates 2 respectively. The first guide wheel 3 and the second guide wheel 4 are also connected by elastic cables 5. The first guide wheel 3 and the second guide wheel 4 maintain a contacting tendency under the action of the elastic cables 5. The gap between the first guide wheel 3 and the second guide wheel 4 forms a hole for the seat belt to pass through.

[0018] In the above structure, the seat belt is pulled out by the retractor and then passes between the first guide wheel 3 and the second guide wheel 4 on the seat belt guide bracket. At this time, the seat belt is limited by the two guide plates 2, the first guide wheel 3 and the second guide wheel 4, making it difficult to come out of the guide bracket. Since the first guide wheel 3 and the second guide wheel 4 are both V-shaped wheels, the seat belt is not easy to come out of the groove of the first guide wheel 3 or the second guide wheel 4 and get stuck in the gap between the guide wheel and the guide plate 2 when the seat belt is pulled. Since the first guide wheel 3 can slide up and down, and the two ends of the first guide wheel 3 and the second guide wheel 4 are connected by an elastic cable 5, even if the seat belt is twisted, it can smoothly push open the first guide wheel 3 and the second guide wheel 4, avoiding the seat belt from getting stuck and unable to be pulled, thereby achieving smooth retraction and pulling of the seat belt.
