Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a backrest cover and foam installation structure adapted to the waist massage function. Background Art

[0002] In order to improve the riding comfort of automobile seats, some manufacturers choose to integrate a massage device inside the seat backrest. During the user's ride, the massage device can massage the user's waist area to relieve the fatigue caused by long sitting and enhance the driving and riding experience. In traditional massage technical solutions, usually, a massage airbag and a mechanical massager are integrated in the waist area of the backrest. The airbag massage uses a soft-textured airbag to act on the user's back area, with a relatively low massage intensity and poor massage effect, making it difficult to comprehensively and deeply relax the user's body. Most mechanical massagers directly massage the user's back by a rotatable massage device. Although the massage intensity is greater than that of the airbag massage, there are also defects such as large volume and complex structure.

[0003] In view of the deficiencies of the traditional technology, the applicant intends to develop a massage device that can simulate kneading, knocking, and pushing techniques. The core of its technology lies in that two massage push arms that can move up and down along their height directions need to be integrated inside the backrest. After the end of the massage push arm acts on the user's waist, the swing of the massage push arm is controlled through a mechanical transmission method to provide kneading and knocking massages. Or, after the end of the massage push arm acts on the user's waist, the up and down movement of the massage push arm is controlled through a lifting structure to provide a pushing massage. In this research and development concept, it should be required that when the massage function is not enabled, the massage push arm can be retracted inside the backrest to maintain a non-ejected state to avoid causing discomfort to the user during normal riding. When the massage function is enabled, the massage push arm needs to be pushed against the inner side of the cover on the front part of the backrest, and when the massage push arm works, the cover will also form a slightly convex state. Therefore, what kind of cover and foam installation method is adopted to better ensure the stable operation and integrated installation of the massage device has become a technical problem that needs to be overcome urgently at present. Summary of the Utility Model

[0004] In view of this, the utility model provides a backrest cover and foam installation structure adapted to the waist massage function, aiming to better accommodate the massage push arm and ensure its stable operation.

[0005] To achieve the above object, the technical solution of the utility model is as follows:

[0006] A backrest cover and foam installation structure adapted to the waist massage function, including a backrest foam, and the key lies in that: a sunken area is provided on the front surface of the backrest foam, and two sets of strip-shaped through grooves extending along the height direction of the backrest are provided in the sunken area, and both sets of strip-shaped through grooves are used to accommodate the massage push arms;

[0007] A wear-resistant cloth is provided on the front side of the backrest foam. The wear-resistant cloth includes a covering layer covering the surface of the backrest foam. A telescopic layer is provided on the rear side of the covering layer, and the telescopic layer is arranged in a folded manner within the sunken area. When the wear-resistant cloth is subjected to an outward thrust from the massage push arm within the strip-shaped through groove, the telescopic layer can be forced to stretch outwards, so that the wear-resistant cloth can bulge outwards.

[0008] With the above structure, when the massage function is enabled, the massage push arm passes through the strip-shaped through groove and the telescopic layer of the ring structure and acts on the inner side of the covering layer. The inner side of the covering layer is subjected to the forward thrust of the massage push arm, which will cause the telescopic layer to unfold outwards. The position of the covering layer corresponding to the massage push arm can bulge outwards adaptively, and there will be no pulling feeling, which can ensure that the massage push arm stably applies massage operations such as kneading, knocking, and massaging.

[0009] Preferably: The telescopic layer is a ring structure and is arranged circumferentially along the sunken area.

[0010] Preferably: The telescopic layer has at least two folding layers. The folding layer located on the outermost side is connected to the covering layer. A transition section is connected to the folding layer located on the innermost side. The transition section is a channel structure and is connected to the groove wall of the strip-shaped through groove.

[0011] Preferably: An inner connection layer is provided at one end of the transition section away from the telescopic layer, and the inner connection layer covers the inner surface of the backrest foam.

[0012] Preferably: Steel wires are embedded in the backrest foam, and the circumferential edge of the covering layer is anchored on the steel wires.

[0013] Preferably: The sunken area is a downwardly concave rectangular groove.

[0014] Preferably: The length of the strip-shaped through groove is less than the length of the sunken area.

[0015] Preferably: A mesh cloth and a sealing plate are provided between the inner connection layer and the inner surface of the backrest foam.

[0016] Preferably: The wear-resistant cloth has elasticity.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] Using the backrest cover and foam installation structure adapted to the waist massage function provided by the present utility model, the massage device is arranged at a position inside the backrest behind the wear-resistant cloth. When the massage device is in the non-working state, the massage push arms are retracted into the strip-shaped through grooves and will not press against the inner side of the wear-resistant cloth. At this time, it can ensure that the covering layer is in a flat state, not only with high appearance quality, but also with good comfort for the user to lean on the backrest normally, without any discomfort. When the massage function is enabled, the massage push arms pass through the strip-shaped through grooves and the telescopic layer of the annular structure and act on the inner side of the covering layer. The inner side of the covering layer is subjected to the forward thrust of the massage push arms, which will cause the telescopic layer to expand outwards. Corresponding to the position of the massage push arms, the covering layer can bulge outwards adaptively without any pulling feeling, and it can ensure that the massage push arms can stably apply massage operations such as kneading, knocking and pushing.

[0026] The present utility model will be further described below in conjunction with the embodiments and the drawings.

[0027] As Figure 1 shown, a backrest cover and foam installation structure adapted to the waist massage function includes a backrest foam 1. A sunken area 1a is provided on the front surface of the backrest foam 1. Two groups of strip-shaped through grooves 1b extending along the height direction of the backrest are provided in the sunken area 1a. Both groups of strip-shaped through grooves 1b are used to accommodate the massage push arms. In this embodiment, the length of the strip-shaped through groove 1b is less than the length of the sunken area 1a. Combining with Figure 2 and 3 shown, a wear-resistant cloth 2 is provided on the front side of the backrest foam 1. The wear-resistant cloth 2 includes a covering layer 2a covering the surface of the backrest foam 1. A telescopic layer 2b is provided on the rear side of the covering layer 2a. From Figure 6It can be seen that the telescopic layer 2b is arranged in the sunken area 1a in a folded manner.

[0028] When the wear-resistant cloth 2 is subjected to the outward thrust of the massage push arm in the strip-shaped through groove 1b, the telescopic layer 2b can be forced to stretch outwards so that the wear-resistant cloth 2 can bulge outwards.

[0029] Combined Figure 7 As shown, during application, the massage device is arranged at a position inside the backrest and behind the wear-resistant cloth 2. When the massage device is in the non-working state, the massage push arm B is retracted into the strip-shaped through groove 1b and will not press against the inner side of the wear-resistant cloth 2. At this time, it can be ensured that the covering layer 2a is in a flat state, and the comfort of the user when normally leaning on the backrest is good without a sense of discomfort. When the massage function is enabled, the massage push arm B passes through the strip-shaped through groove 1b and the telescopic layer 2b of the annular structure and acts on the inner side of the covering layer 2a. When the inner side of the covering layer 2a is subjected to the forward thrust of the massage push arm B, the telescopic layer 2b will expand outwards, corresponding to the position of the massage push arm B, and can bulge outwards adaptively without any pulling feeling, ensuring that the massage push arm B can stably apply massage operations such as kneading, knocking, and pushing.

[0030] Furthermore, as again Figure 3 and 5 shown, the telescopic layer 2b is an annular structure and is arranged circumferentially along the sunken area 1a. Designed in this way, when the massage push arm B presses against the inner side of the covering layer 2a, the telescopic layer 2b can expand outwards better.

[0031] Please refer Figure 4 , the telescopic layer 2b has at least two folded layers a, and the outermost folded layer a is connected to the covering layer 2a. Combined Figure 3 shown, there is a transition section b connected to the innermost folded layer a. The transition section b is arranged in two groups along the width direction of the covering layer 2a, and the transition section b is a channel structure adapted to the strip-shaped through groove 1b. Referring to Figure 5 , each group of transition sections b is connected to the groove wall of the corresponding strip-shaped through groove 1b. When the massage push arm B is pushed forward, it can first act on the inner surface of the covering layer 2a through the transition section b.

[0032] Such as Figure 3 shown, an inner connection layer c is provided at one end of the transition section b away from the telescopic layer 2b. From Figure 5 it can be seen that the inner connection layer c covers the inner surface of the backrest foam 1, ensuring that when the massage push arm B applies an outward thrust to the covering layer 2a, the wear-resistant cloth 2 is always fixedly connected to the backrest foam 1.

[0033] Furthermore, as again Figure 6 shown, a steel wire 3 is embedded in the backrest foam 1, and the circumferential edge of the covering layer 2a is anchored on the steel wire 3. Designed in this way, the circumferential connection stability of the covering layer 2a and the backrest foam 1 is ensured.

[0034] Please refer Figure 1 and 6 In order to ensure the flatness of the front surface of the wear-resistant cloth 2 when the massage device is not working and improve the comfort of the user during normal sitting, in this embodiment, the sunken area 1a is a downwardly concave rectangular groove, and the thickness of the telescopic layer 2b is adapted to the thickness of the circumference of the sunken area 1a.

[0035] In this embodiment, the wear-resistant cloth 2 is elastic. With such a design, when the massage ends, the wear-resistant cloth 2 can return to a flat state.

[0036] Refer again Figure 5 and 6 Between the inner connection layer c and the inner surface of the backrest foam 1, there are a mesh cloth 4 and a sealing plate 5. With such consideration, the reliability and tightness of the connection between the wear-resistant cloth 2 and the inside of the backrest foam 1 are improved.

[0037] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Under the inspiration of the present invention, those of ordinary skill in the art can make various similar representations without violating the purpose and claims of the present invention. Such transformations all fall within the protection scope of the present invention.
