Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an adjustable horizontal car seat backrest tray. Background Technology

[0002] Car seatback tray tables are a very practical in-car accessory. Installed behind the front seats, they not only provide passengers with extra work or dining space, but can also be used to place items such as food, mobile phones, and laptops. These tray tables are usually pre-installed at the factory or added as an aftermarket installation on the back of the front seats.

[0003] The most basic function of the tray table is that, when not in use, it folds down to a position parallel to the back of the car seat via a linkage assembly. When in use, it unfolds to a horizontal position facing the rear passengers. Furthermore, through the product's design, the tray table is horizontal when the linkage assembly is fully extended.

[0004] However, the backrest angle of the front seats in a car can be adjusted to make the front passenger experience more comfortable. However, as the backrest angle of the front seats is adjusted, the angle of the rear seat tray tables will also change, and they cannot remain horizontal. The tray tables, tilted upwards or downwards, will affect the user experience of rear passengers. If the tray tables are fixed to the base of the front seats, rather than to the backrests, they will not be affected by the backrest angle adjustment. However, in most cases, fixing the tray tables to the backrests of the front seats achieves a more aesthetically pleasing and secure design.

[0005] Therefore, the small table on the back of the car seat needs to have a horizontal angle adjustment function to ensure that the small table can still be in a horizontal position after the backrest angle of the front seat is adjusted. Utility Model Content

Detailed Implementation

[0031] To better illustrate the purpose, technical solution, and advantages of this utility model, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0032] like Figures 1 to 8 The diagram shows an adjustable horizontal car seat backrest tray according to an embodiment of the present invention. The car seat backrest tray includes a mounting module, a tray body 20, and a linkage assembly 30. The mounting module is fixed to the back of the car seat and provides space for the tray body 20. In this embodiment, the mounting module is configured as the backrest body 10; in other embodiments, it can be a simple mounting bracket. The backrest body 10 can be configured in the shape of a car seat backrest, making the car seat more aesthetically pleasing, while also accommodating the tray body 20. The tray body 20 provides a place for items and is connected to the backrest body 10 via the linkage assembly 30. To make the tray body 20 more robust and stable, the linkage assembly 30 is typically configured in two sets, each set having two links: an upper link 31 and a lower link 32. The two ends of the upper link 31 are hinged to the upper side of the backrest body 10 and the rear side of the tray body 20, respectively. The two ends of the lower connecting rod 32 are respectively hinged to the lower side of the back panel body 10 and the front side of the table body 20. The upper connecting rod 31 and the lower connecting rod 32 cooperate with each other. When the upper connecting rod 31 and the lower connecting rod 32 swing to the lower limit position, the table body 20 is displaced and retracted into the receiving groove. When the upper connecting rod 31 and the lower connecting rod 32 swing to the upper limit position, the upper connecting rod 31 and the lower connecting rod 32 abut against each other, and at the same time, the table body 20 is displaced and unfolded outside the receiving groove, maintaining a horizontal state facing the passenger.

[0033] To achieve the technical objective of this utility model, specifically, the upper connecting rods 31 of the connecting rod assemblies 30 on both sides are respectively provided with adjusting sliders 40. Positioning blocks 21 are respectively provided on the tabletop body 20 at positions corresponding to the connecting rod assemblies 30 on both sides. The adjusting slider 40 is equipped with a sliding operation part 41 exposed on the upper connecting rod 31, and a wedge-shaped part 42 is provided on the side of the adjusting slider 40 facing the tabletop body 20. The wedge-shaped part 42 cooperates with the positioning blocks 21 so that as the sliding operation part 41 moves, the wedge-shaped part 42 abuts against the positioning blocks 21 at different positions, and correspondingly changes the distance between the upper connecting rod 31 and the positioning blocks 21.

[0034] refer to Figure 1 When adjusting the small table on the back of the car seat, the user holds the table body 20 with both hands, places their fingers on the exposed sliding control part 41, and moves the sliding control part 41 forward or backward. (See also...) Figures 5 to 8 The wedge-shaped portion 42 changes position with the sliding operation portion 41, and positions of different thicknesses of the wedge-shaped portion 42 abut against the positioning block 21. If the wedge-shaped portion 42 moves backward, the thicker position abuts against the positioning block 21; if the wedge-shaped portion 42 moves forward, the thinner position abuts against the positioning block 21. The thicker the position abutting against the positioning block 21, the farther the distance between the upper connecting rod 31 and the positioning block 21, and correspondingly, the larger the minimum angle between the upper connecting rod 31 and the tabletop body 20, causing the tabletop body 20 to adjust upward at the abutment point. Similarly, the thinner the position abutting against the positioning block 21, the closer the distance between the upper connecting rod 31 and the positioning block 21, and correspondingly, the smaller the minimum angle between the upper connecting rod 31 and the tabletop body 20, causing the tabletop body 20 to adjust downward at the abutment point.

[0035] When in use, the greater the angle of the front seat back, the more the unadjusted front table body 20 will tilt downwards. Therefore, it is necessary to move the sliding operation part 41 backwards so that the thicker wedge part 42 abuts against the positioning block 21, and the table body 20 tilts upwards, thereby keeping the table body 20 in a horizontal position.

[0036] Therefore, this utility model can adjust the angle of the table body 20 relative to the angle of the front seat back of the car, thereby keeping the table body 20 horizontal and improving the table usage experience for rear users. Meanwhile, the adjusting slider 40 is located on the upper connecting rod 31, and the sliding operation part 41 is prominently positioned, making its function easily understandable to the user. Adjusting the table body 20 is simple. With both hands, the table body 20 can be moved first, and then the sliding operation part 41 can be moved, achieving a labor-saving effect.

[0037] To keep the horizontal adjustment stable, refer to Figure 3Specifically, in this embodiment, the wedge-shaped portion 42 of the adjusting slider 40 is provided with multiple toothed grooves on the side facing the table body 20. Each toothed groove is distributed along the slope at the bottom of the wedge-shaped portion 42. The top of the positioning block 21 is configured as a pointed tip, which engages with the toothed groove of the adjusting slider 40. Thus, when the adjusting slider 40 is moved, the pointed tip of the positioning block 21 will engage with the toothed grooves at different slope heights, and the distance between the upper connecting rod 31 and the positioning block 21 will change accordingly.

[0038] To improve the experience of level adjustment, refer to Figure 3 In this embodiment, the interior of the wedge-shaped part 42 is provided with a groove that opens toward the side of the table body 20. The groove is provided with a wedge-shaped block 421 made of elastic material. The wedge-shaped block 421 is also provided with a toothed groove. When in use, the bottom of the wedge-shaped block 421 will protrude from the bottom of the wedge-shaped part 42 and preferentially abut against the tip of the positioning block 21. During the contact process, the elastic force is released, thereby achieving a silent effect.

[0039] refer to Figure 3 Specifically, in this embodiment, the upper connecting rod 31 is provided with an inner cavity, and the inner cavity is provided with a strip-shaped opening. The adjusting slider 40 is provided with a neck 43 connecting the sliding operation part 41 and the wedge-shaped part 42. The neck 43 is linearly slidable within the strip-shaped opening. The sliding operation part 41 is engaged with the upper surface of the strip-shaped opening, and the top of the wedge-shaped part 42 is engaged with the lower surface of the strip-shaped opening, thereby ensuring that the adjusting slider 40 can stably slide linearly along the strip-shaped opening, thus making the sliding of the adjusting slider 40 smoother.

[0040] refer to Figure 3 In this embodiment, the wedge-shaped portion 42 is disposed within the inner cavity, thereby concealing the wedge-shaped portion 42 within the upper connecting rod 31. A through-hole is provided at the bottom of the inner cavity, through which the positioning block 21 extends into the inner cavity and abuts against the wedge-shaped portion 42.

[0041] In this embodiment, the sliding operation part 41 is configured as a longitudinally extending arc-shaped strip, and the upper surface of the sliding operation part 41 is provided with transversely extending ribs, thereby improving the friction of the push-pull adjustment slider 40.

[0042] refer to Figure 3 Specifically, in this embodiment, the upper connecting rod 31 is provided with a groove that opens to one side, and the upper connecting rod 31 is provided with a cover plate 44. The groove of the upper connecting rod 31 and the cover plate 44 cooperate to form an inner cavity, a strip-shaped opening, and a through-hole. The cover plate 44 facilitates the installation of the adjustable slider 40.

[0043] refer to Figure 3 In this embodiment, the wedge-shaped portion 42 has a protrusion 422 on its sidewall, which abuts against the inner cavity sidewall of the upper connecting rod 31. The protrusion 422 reduces the sliding friction of the adjusting slider 40.

[0044] Specifically, in this embodiment, the positioning block 21 is equipped with an abutment portion and two feet, each foot being fixedly connected to the table body 20 along the front and back of the hinge rotation face. The two feet of the positioning block 21 can better support the upper connecting rod 31, and the front and back distribution of the feet along the hinge rotation face means that they are located on the swing plane of the upper connecting rod 31, thereby better transmitting the supporting force to the table body 20.

[0045] The above embodiments mainly describe the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
