Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, and more particularly to a structure for freely controlling the tension of the skin suspension and a seat having the same structure. Background Technology

[0002] With the development of the automotive industry and people's increasing demands for ride comfort, the design and manufacturing processes of car seats are also constantly being improved. As the part that comes into direct contact with occupants, the tension of the seat cover directly affects the appearance quality and ride comfort of the seat.

[0003] Traditional seat upholstery tensioning structures typically employ a fixed tensioning method. This means the upholstery is fixed to the seat frame via tension straps, clips, or wires. The tension of the upholstery is fixed after the seat is manufactured and cannot be adjusted during use. For example, existing upholstery tensioning structures often use non-woven fabric wire clips sewn onto the upholstery and then connected to the seat frame via connectors; or they use tension plates passing through through holes in the foam to tighten the upholstery. While these solutions achieve the basic tensioning function of the upholstery, the fixed tension cannot be adjusted according to the occupant's sitting posture or individual needs.

[0004] Furthermore, with the diversification of seat functions, many seats are equipped with adjustable devices such as airbags. Because the tension of the seat upholstery is not adjustable, the airbag's ability to rise is limited by the tension of the upholstery, thus restricting the height of the airbag and affecting the seat's support adjustment effect.

[0005] Therefore, there is an urgent need in the existing technology for a technical solution that can freely control the tension of the seat cover to solve the problem that the tension of the traditional seat cover cannot be adjusted, improve the seat comfort, and solve the problem of limited airbag height. Summary of the Invention

[0006] To address the aforementioned problems in the prior art, this invention provides a structure and seat with freely controllable skin tension, allowing for flexible adjustment of the skin tension as needed during use. Through the coordinated operation of components such as the motor, turntable structure, skin, and seat, this invention enables the seat to have a freely controllable skin tension structure, solving the problem of non-adjustable skin tension in traditional seats, thus improving seating comfort. Furthermore, adjusting the skin tension also solves the problem of limited airbag height.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A structure for freely controlling the tension of a seat upholstery includes a seat upholstery tension strip, a seat upholstery hook, a motor, a backrest support plate, a turntable, and a turntable bracket. One end of the seat upholstery tension strip is connected to the seat upholstery. The turntable bracket is fixed to the backrest support plate, and the motor is fixed to the turntable bracket. The turntable is connected to the output end of the motor and is driven to rotate by the motor. The other end of the seat upholstery tension strip passes through the seat foam and is fixed to the turntable by the seat upholstery hook. The motor is connected to the vehicle control system and rotates after receiving the vehicle control signal, driving the turntable to rotate. The tension of the seat upholstery is controlled by the winding or releasing of the seat upholstery tension strip.

[0022] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Example 1

[0023] Reference Figures 1 to 3 , Figure 1 This is an exploded view of an example of the present invention. Figure 2 This is a perspective view of the skin not being tightened after application of this invention. Figure 3 This is a perspective view of the seat upholstery in its tightened state after application in an example of the present invention. The present invention provides a structure for freely controlling the tightness of the seat upholstery, including a seat upholstery tensioning strip 1, a seat upholstery hook 2, a motor 3, a backrest support plate 4, a turntable 5, and a turntable bracket 6. One end of the seat upholstery tensioning strip 1 is connected to the seat upholstery. Several seat upholstery tensioning strips 1 are provided, arranged symmetrically on the left and right sides. Preferably, there are 3 seat upholstery tensioning strips 1 on each side. The turntable bracket 6 is fixed to the backrest support plate 4. Preferably, the turntable bracket 6 is fixed to the backrest support plate 4 by bracket screws 61. The motor 3 is fixed to the turntable bracket 6. Preferably, the motor 3 is fixed to the turntable bracket 6 by motor fixing screws 31. The turntable 5 is connected to the output end of the motor 3 and is driven to rotate by the motor 3. The turntable 5 and the output end of the motor 3 are preferably installed in an interference fit manner. The other end of the skin tensioning strip 1 passes through the seat foam and is fixed to the turntable 5 by the skin hanging nail 2. In one embodiment, the turntable 5 is provided with a plurality of fixing holes 51 for fixing the skin tensioning strip 1. The skin hanging nail 2 fixes one end of the skin tensioning strip 1 to the fixing hole 51. The motor 3 is connected to the vehicle control system signal. After receiving the vehicle control signal, it rotates and drives the turntable 5 to rotate. The tightness of the skin tensioning strip is controlled by the winding or releasing of the skin tensioning strip 1. Example 2

[0024] In another application scenario of the present invention, when the seat is equipped with an adjustment device such as an airbag, by controlling the motor 3 to appropriately loosen the tension of the skin, more space can be provided for the airbag to be lifted, thus solving the problem of limited airbag lifting height; when the airbag is not required to be lifted over a large area, the tension of the skin can be appropriately tightened to enhance the seat's wrapping feel.

[0025] The present invention also provides a seat, including a structure for freely controlling the tension of the skin as described in any of the preceding claims. The seat is a vehicle seat, and the motor 3 is signal-connected to the vehicle's overall controller, adjusting the tension of the skin according to the vehicle control signal. Furthermore, the seat also includes an air bag (not shown) disposed between the skin and the foam, the height of which is changed by adjusting the tension of the skin.

[0026] The following will refer to Figures 1 to 3 The working principle of the present invention will be explained.

[0027] When the occupants need to adjust the tension of the skin suspension via the vehicle control system, the vehicle control system sends a control signal to motor 3. Upon receiving the signal, motor 3 starts rotating, driving the turntable 5, which is interference-fitted with it, to rotate. As the turntable 5 rotates, the skin suspension bar 1 fixed to it is wound or released accordingly.

[0028] like Figure 2 The diagram shows the skin in an unstressed state. When turntable 5 rotates in the release direction, the skin tensioning bar 1 is released, and the skin is in a relaxed state. Figure 3 The diagram shown illustrates the skin tension state. When the turntable 5 rotates in the winding direction, the skin tensioning bar 1 is wound and tightened, and the skin is in a tensioned state.

[0029] Thus, this invention enables free control of the tension of the seat cover, allowing passengers to adjust the tension of the cover at any time according to their personal preferences or riding needs, thereby obtaining a better riding experience.

[0030] This invention provides a freely controllable leather upholstery tension structure and seat, solving the problem of non-adjustable leather upholstery tension in traditional seats. It allows the seat to freely adjust the tightness of the leather upholstery tension according to the occupant's needs or seating position during use, thus improving seating comfort. Furthermore, this invention addresses the limitation on airbag lift height by adjusting the leather upholstery tension. When greater airbag support height is needed, the leather upholstery tension can be appropriately loosened to provide more space for airbag lift; when a stronger sense of enclosure is required, the leather upholstery tension can be appropriately tightened.

[0031] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
