Description

Technical Field

[0001] The present invention belongs to the technical field of seat decoration, and particularly relates to an adjustable buckling structure for seat concave patterns. Background Art

[0002] With the improvement of people's living standards, the ownership of cars has been increasing year by year. At the same time, with the popularization of cars, more and more people have different requirements for car interiors. In car decoration, the decoration of car seats and other structures has a great impact on the driving experience. At the same time, some technologies and decorations on household sofas have gradually been applied to car seats. For example, the concave pattern structure in some sofa structures, when applied to car seats, can effectively improve the aesthetic feeling of car seats, and at the same time can form gaps to reduce the contact between the seat surface or chair surface and the human skin, thus facilitating sweating during driving.

[0003] Since the existing concave pattern structures of seats are all formed by tying and pulling the seat surface with fixed ropes, during the process of tying the fixed ropes, due to the rebound force formed after the sponge is extruded, after the fixed ropes pull the seat to form the concave pattern structure, they will continuously bear the elastic force of the sponge. When tying a knot, the force of the human hand pulling the fixed rope will change, which will cause the position of the knot of the fixed rope to deviate from the expected position. As a result, the depth of the concave pattern structure formed will be different. And if you want to untie the fixed rope and remake the concave pattern structure, you need to repeat the above process, and there will still be a problem that the depths of the concave pattern structures are not the same.

[0004] Therefore, it is necessary to design a buckling structure that can conveniently adjust the depth of the concave pattern structure to replace the fixed rope, so as to facilitate the uniformity of the depths of several concave pattern structures on the seat surface. Summary of the Invention

[0005] In order to solve the problem that it is difficult to unify the depths of the concave pattern structures on the existing seat surface, this solution provides an adjustable buckling structure for seat concave patterns.

[0006] The technical solution adopted by the present invention is as follows:

[0007] An adjustable buckling structure for seat concave patterns, which is used to be installed on the seat cushion main body of a seat to form a concave pattern structure in the shape of a pit on the seat surface of the seat cushion main body, including a buckle cap, a buckle strap and a buckle piece; the buckle cap is arranged at one end of the buckle strap and can drive a part on the seat surface to be concave inward, so as to form a concave pattern structure; the other end of the buckle strap penetrates to the bottom side of the seat cushion main body and is connected to the buckle piece, and the relative position of the buckle strap and the buckle piece can be adjusted unidirectionally to adjust the depth of the concave pattern structure. In the above structure, since elastic materials such as sponge are used inside the seat cushion main body, when the buckle cap is used to squeeze the seat surface of the seat inward, a concave pattern structure can be formed on the seat surface, and the depth of the concave pattern structure is determined by the position of the buckle cap. Since the buckle piece is abutted against the bottom surface of the seat, the depth of the concave pattern structure is directly determined by the length of the buckle strap between the buckle piece and the buckle cap. Since the relative position of the buckle strap and the buckle piece can be adjusted unidirectionally, when making the concave pattern structure, the depth of the concave pattern structure is adjusted by adjusting the relative position of the buckle strap and the buckle piece.

[0008] As a supplementary design or alternative structure of the above adjustable buckling structure for seat concave patterns: the buckle strap is flat, and serrated first tooth patterns are arranged on one side of the buckle strap; a jack is arranged on the buckle piece, and anti-retreat teeth are arranged inside the jack; when the buckle strap is inserted into the jack, the anti-retreat teeth are engaged and matched with the first tooth patterns. The anti-retreat teeth can use the first tooth patterns on the buckle strap to be in inclined plane cooperation with the anti-retreat teeth when the buckle strap is pulled unidirectionally, so as to disengage from the engaged state and form a new engaged state with another first tooth pattern. In this way, reciprocating, the unidirectional position adjustment of the buckle piece along the buckle strap can be realized, and the buckle strap is prevented from coming out of the jack of the buckle piece.

[0009] As a supplementary design or alternative structure of the above adjustable buckling structure for seat concave patterns: the anti-retreat teeth are strip-shaped, one end of the anti-retreat teeth is connected to the hole wall on one side of the jack, and the other end of the anti-retreat teeth has second tooth patterns that are engaged and matched with the first tooth patterns.

[0010] As a supplementary design or alternative structure of the above adjustable buckling structure for seat concave patterns: the tooth tip direction of the second tooth pattern faces the buckle cap.

[0011] As a supplementary design or alternative structure of the above adjustable buckling structure for seat concave patterns: the anti-retreat teeth can bend and rebound, so that the other end of the anti-retreat teeth can swing in the jack; the other end of the anti-retreat teeth extends towards the hole wall on the other side of the jack in the natural state, so that the second tooth patterns are engaged and matched with the first tooth patterns; when the other end of the anti-retreat teeth swings towards one side of the jack, the second tooth patterns are disengaged from the engaged state with the first tooth patterns.

[0012] As a supplementary design or alternative structure to the adjustable buckling structure of the above-mentioned seat embossing: the pointing direction of the other end of the anti-retreat tooth is away from the buckle cap. Due to this structure, the second tooth pattern at the other end of the anti-retreat tooth can be caught in the tooth hook of the first tooth pattern, effectively preventing the buckle belt from disengaging from the jack.

[0013] As a supplementary design or alternative structure to the adjustable buckling structure of the above-mentioned seat embossing: the seat cushion body includes a main elastic layer and an upper elastic layer; the upper elastic layer is attached to the upper surface of the main elastic layer, and the seat surface is attached to the upper surface of the upper elastic layer.

[0014] As a supplementary design or alternative structure to the adjustable buckling structure of the above-mentioned seat embossing: the buckle cap is detachably connected to or integrally formed with the buckle belt, and the other end of the buckle belt is tapered.

[0015] As a supplementary design or alternative structure to the adjustable buckling structure of the above-mentioned seat embossing: the buckle belt is made of a plastic strip, and the buckle belt can be bent along its length direction. If the buckle belt is made of a plastic strip, the manufacturing cost of the embossing structure will be greatly reduced. At the same time, because the plastic strip has a certain elasticity in the length direction, the buckle belt can be bent in the length direction, thereby reducing the situation where the pressure applied to the buckle cap pushes the buckle belt into the buckle piece.

[0016] As a supplementary design or alternative structure to the adjustable buckling structure of the above-mentioned seat embossing: a plurality of reserved holes penetrating the seat cushion body are prefabricated on the seat cushion body, and the buckle belt penetrates through the reserved holes to the bottom side of the seat cushion body; the depth of the embossing structure is adjusted by adjusting the distance between the buckle piece and the buckle cap.

[0017] The beneficial effects of the present invention are:

[0018] In the structure of this solution, under the pulling force of the buckle belt, the buckle cap presses down the seat surface, thereby forming an embossing structure on the seat surface. Since the buckle belt and the buckle piece adopt an adjustable connection structure, the distance between the buckle piece and the buckle cap can be adjusted, thereby realizing the adjustment of the depth of the embossing structure; in this solution, the anti-retreat tooth can, when the buckle belt is pulled unidirectionally, use the first tooth pattern on the buckle belt to cooperate with the anti-retreat tooth in an inclined plane, so as to disengage from the engaged state and form a new engaged state with another first tooth pattern. Repeating like this can realize the unidirectional position adjustment of the buckle piece along the buckle belt and prevent the buckle belt from disengaging from the jack of the buckle piece; while using the anti-retreat tooth provided on the buckle piece to cooperate with the second tooth pattern provided on the buckle belt, the buckle belt can also be pulled unidirectionally through the structure of the inclined plane cooperation, thereby realizing the simple adjustment of the distance between the buckle piece and the buckle cap, and further ensuring the convenience when adjusting the depth of the embossing structure.

Specific implementation manners

[0024] The following will clearly and completely describe the technical solutions in this embodiment with reference to the drawings. The described embodiments are only a part of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of this solution.

[0025] Embodiment 1

[0026] The concave pattern structure 12 of the seat is a decorative structure provided on an elastic seat cushion or seat backrest, which can effectively improve the aesthetic feeling of the seat, and at the same time can form voids to reduce the contact between the seat surface 11 or the chair surface and the human skin, thus being beneficial to sweating during driving.

[0027] In the manufacturing process of the concave pattern structure 12, the concave pattern structure 12 is often formed by tying and pulling the seat surface 11 with a fixing rope. During the process of tying the fixing rope, due to the rebound force formed after the sponge is extruded, when the fixing rope pulls the seat to form the concave pattern structure 12, since the traction force of the human hand on the fixing rope will change during tying, the position of the knot of the fixing rope will deviate from the expected position, resulting in different depths of the concave pattern structure 12 formed. Eventually, the size and depth of the concave pattern structure 12 are not uniform, affecting the aesthetics. Thus, to manufacture the concave pattern structure 12 with uniform shape and size will consume a large amount of manpower and material resources, and at the same time, there will be a phenomenon of repeated operations, seriously affecting the production and manufacturing efficiency, and having higher requirements for the experience of the personnel manufacturing the concave pattern structure 12. In addition, even when the size and depth of the concave pattern structure 12 are uniform, the depth of the concave pattern structure 12 may be adjusted according to different personal preferences. During the secondary adjustment process, the concave pattern structure manufactured by the existing technology can only be achieved by destroying the fixing rope of the original structure and cannot be achieved through simple adjustment.

[0028] In order to achieve the uniformity of the depth and size of different concave pattern structures 12 on the seat, this embodiment designs an adjustable buckling structure for the seat concave pattern structure 12, as Figures 1 to 3 shown.

[0029] The adjustable buckling structure in this embodiment is used to be installed on the seat cushion main body 1 of the seat to form a concave pit-shaped concave pattern structure 12 on the seat surface 11 of the seat cushion main body 1, and includes components such as a buckle cap 21, a buckle belt 22, and a buckle piece 23. Since the seat cushion main body 1 is internally made of elastic materials such as sponge, when the buckle cap 21 is used to squeeze the seat surface 11 of the seat inward, a concave pattern structure 12 can be formed on the seat surface 11, and the depth of the concave pattern structure 12 is determined by the position of the buckle cap 21. Since the buckle piece 23 needs to abut against the bottom side of the seat cushion main body 1, the depth of the concave pattern structure 12 is directly determined by the length of the buckle belt 22 between the buckle piece 23 and the buckle cap 21. Since the relative position of the buckle belt 22 and the buckle piece 23 can be adjusted unidirectionally, when manufacturing the concave pattern structure 12, the depth of the concave pattern structure 12 can be adjusted by adjusting the relative position of the buckle belt 22 and the buckle piece 23.

[0030] The buckle cap 21 is arranged at one end of the buckle belt 22. The buckle cap 21 and the buckle belt 22 can adopt a detachable connection structure or the two can also be set as a whole. The other end of the buckle belt 22 is conical. The buckle cap 21 can drive a part on the seat surface 11 to be concave, thereby forming the concave pattern structure 12. The buckle cap 21 can adopt a round cake-shaped structure, and the thickness of the middle part of the buckle cap 21 is greater than the thickness of the edge, so as to reduce the damage of the buckle cap 21 to the seat surface 11.

[0031] The other end of the buckle belt 22 penetrates to the bottom side of the seat cushion body 1 and is connected to the buckle piece 23. The relative position of the buckle belt 22 and the buckle piece 23 can be adjusted unidirectionally to adjust the depth of the concave pattern structure 12. The buckle belt 22 is flat, and a serrated first tooth pattern is provided on one side of the buckle belt 22; a jack 231 is provided on the buckle piece 23, and an anti-retreat tooth 232 is provided inside the jack 231; when the buckle belt 22 is inserted into the jack 231, the anti-retreat tooth 232 engages with the first tooth pattern. The buckle belt 22 can be made of a plastic strip, and the buckle belt 22 can be bent along its length direction. If the buckle belt 22 is made of a plastic strip, the manufacturing cost of the concave pattern structure 12 will be greatly reduced. At the same time, because the plastic strip has a certain bending elasticity in the length direction, the buckle belt 22 can be bent in the length direction, so as to prevent the buckle cap 21 from pushing the buckle belt 22 into the buckle piece under pressure.

[0032] The anti-retreat tooth 232 is strip-shaped. One end of the anti-retreat tooth 232 is connected to the hole wall on one side of the jack 231, and the other end of the anti-retreat tooth 232 has a second tooth pattern that engages with the first tooth pattern. The tooth tip direction of the second tooth pattern faces the buckle cap 21. The anti-retreat tooth 232 can bend and rebound, so that the other end of the anti-retreat tooth 232 can swing in the jack 231; when the other end of the anti-retreat tooth 232 is in the natural state, it extends towards the hole wall on the other side of the jack 231, and its pointing direction is away from the buckle cap 21, so that the second tooth pattern engages with the first tooth pattern; when the other end of the anti-retreat tooth 232 swings towards one side of the jack 231, the second tooth pattern disengages from the first tooth pattern.

[0033] The buckle piece can adopt a square sheet or circular sheet structure, and the outer diameter of the buckle piece is generally larger than the outer diameter of the buckle cap 21, so as to reduce the formation of a deeper concave pit on the bottom surface of the seat body.

[0034] The seat cushion body 1 includes a main elastic layer 14 and an upper elastic layer 13; the upper elastic layer 13 is attached to the upper surface of the main elastic layer 14, and the seat surface 11 is attached to the upper surface of the upper elastic layer 13. A plurality of reserved holes penetrating the seat cushion body 1 are prefabricated on the seat cushion body 1, and the buckle belt 22 penetrates to the bottom side of the seat cushion body 1 along the reserved holes; the depth of the concave pattern structure 12 is adjusted by adjusting the distance between the buckle piece 23 and the buckle cap 21.

[0035] When the buckle structure in this embodiment is in use, the end of the buckle strap 22 away from the buckle cap 21 is inserted through the reserved hole opened on the seat cushion main body 1 and penetrates to the bottom surface of the seat cushion. Then, the end of the buckle strap 22 is inserted into the insertion hole 231 of the buckle piece 23. The first tooth pattern on the buckle strap 22 can engage and cooperate with the second tooth pattern on the buckle piece 23, thereby restricting the buckle strap 22 from detaching from the buckle piece 23. Since the second tooth pattern is serrated, when the buckle strap 22 is pulled unidirectionally to make the buckle piece 23 approach the buckle cap 21, the inclined surface mating structure between the first tooth pattern and the second tooth pattern causes the first tooth pattern and the second tooth pattern to temporarily disengage from the engaged state. After the state of disengaging from the inclined surface mating, another first tooth pattern engages with the second tooth pattern on the anti-push tooth, and reciprocally cooperates, thereby forming a unidirectional pulling structure between the buckle strap 22 and the buckle piece. Since the second tooth pattern on the buckle piece can form an engaging and cooperating relationship with the first tooth pattern at any position in the length direction of the buckle strap 22, when the buckle piece is lower than the bottom surface of the seat main body and the buckle cap 21 abuts against the seat surface 11 of the seat cushion main body, the concave pattern structure 12 can be formed by the extrusion of the buckle cap 21 on the seat surface 11. The depth of the concave pattern structure 12 can be determined by the engaging position of the anti-retreat tooth 232 and the buckle strap 22. When the depth of the concave pattern structure 12 is too large, the buckle strap 22 can be cut off with scissors and a new buckle strap 22 can be selected to make the concave pattern structure 12, or a needle-like tool can be used to lift the anti-retreat tooth 232, so that the first tooth pattern and the second tooth pattern are disengaged from the engaged state, facilitating the withdrawal of the buckle strap 22 from the insertion hole 231.

[0036] Embodiment 2

[0037] As Figure 2 shown, this embodiment designs an anti-retreat structure capable of unidirectional pulling. The anti-retreat structure includes a buckle piece and a buckle strap 22. The other end of the buckle strap 22 is conical, and the conical end of the buckle strap 22 can be connected to the buckle piece 23. The relative position of the buckle strap 22 and the buckle piece 23 can be adjusted unidirectionally.

[0038] The buckle strap 22 is flat, and a serrated first tooth pattern is provided on one side of the buckle strap 22; an insertion hole 231 is provided on the buckle piece 23, and an anti-retreat tooth 232 is provided inside the insertion hole 231; when the buckle strap 22 is inserted into the insertion hole 231, the anti-retreat tooth 232 engages and cooperates with the first tooth pattern. The buckle strap 22 can be made of a plastic strip, and the buckle strap 22 can be bent along its length direction.

[0039] The anti-withdrawal tooth 232 is strip-shaped. One end of the anti-withdrawal tooth 232 is connected to the hole wall on one side of the jack 231, and the other end of the anti-withdrawal tooth 232 has a second tooth pattern that engages with the first tooth pattern. The anti-withdrawal tooth 232 can bend and rebound, enabling the other end of the anti-withdrawal tooth 232 to swing within the jack 231; when the other end of the anti-withdrawal tooth 232 is in its natural state, it extends towards the hole wall on the other side of the jack 231, so that the second tooth pattern engages with the first tooth pattern; when the other end of the anti-withdrawal tooth 232 swings towards one side of the jack 231, the second tooth pattern disengages from the first tooth pattern.

[0040] The buckle piece can adopt a square sheet or circular sheet structure.

[0041] When the anti-withdrawal structure in this embodiment is in use, the tapered end of the buckle belt 22 is inserted into the jack 231 of the buckle piece 23. The first tooth pattern on the buckle belt 22 can engage with the second tooth pattern on the buckle piece 23, thereby restricting the buckle belt 22 from detaching from the buckle piece 23. Since the second tooth pattern is serrated, when the buckle belt 22 is pulled unidirectionally to the right, the inclined surface mating structure between the first tooth pattern and the second tooth pattern causes the first tooth pattern and the second tooth pattern to be temporarily disengaged from the engaged state. After the state of disengaging from the inclined surface mating, another first tooth pattern engages with the second tooth pattern on the anti-push tooth, and reciprocatingly cooperates, thereby forming a unidirectional pulling structure between the buckle belt 22 and the buckle piece. Since the second tooth pattern on the buckle piece can form an engaging relationship with the first tooth pattern at any position in the length direction of the buckle belt 22, when it is necessary to withdraw the buckle belt 22 from the jack 231, a needle-like tool can be used to lift the anti-withdrawal tooth 232, so that the first tooth pattern and the second tooth pattern are disengaged from the engagement, facilitating the withdrawal of the buckle belt 22 from the jack 231.

[0042] The above embodiments are merely examples for clear illustration and are not limitations on the implementation manners; it is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present technology.
