Description

Technical Field

[0001] This utility model relates to the field of detachable backrest cushions for use with chairs, and in particular to a foldable dual-purpose backrest cushion. Background Technology

[0002] A massage backrest is an additional cushion placed between the backrest and lumbar region of a seat. On the one hand, it can compensate for the inability of the backrest shape to fully conform to the lumbar region. On the other hand, it is equipped with a massage mechanism to massage the lumbar region during use, achieving the technical effect of adding a massage function to a regular seat, thus meeting the needs of many consumers.

[0003] However, in practical applications, it was found that massage cushions with massage functions, when installed on ordinary chairs, only have one massage mode: when a massage is needed, the massage device can be turned on to massage the lower back. When the user needs to rest and stop the massage, although the massage function is turned off, the massage device still presses against the lower back, causing severe discomfort and significantly affecting the user experience. Removing the entire massage cushion also fails to provide overall lumbar support, requiring the replacement with an ordinary cushion, resulting in high operating costs and obvious defects. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a foldable dual-purpose cushion that can be used as a massage cushion and can also be converted into a regular cushion by flipping it over.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a foldable dual-purpose cushion, including a cushion body, a movable massage head fixedly installed inside the cushion body, and a massage mechanism for driving the movable massage head to perform massage actions. Both sides of the cushion body are provided with side wings that can be folded back and forth relative to the cushion body. A bendable shaping component is fixedly installed inside the cushion body, and the two ends of the bendable shaping component extend into the two side wings respectively.

[0006] Preferably, both ends of the bendable shaping component are fixedly provided with mounting plates, which are fixedly connected to the side wings.

[0007] Preferably, the flexible shaping component is a bend-resistant metal hose or a fold-resistant gooseneck tube.

[0008] Preferably, the two side wings are located at the lower part of the edge.

[0009] Preferably, the connection between the side wing and the main body of the cushion is provided with a bend line, and the distance between the two bend lines is less than the width of the top of the cushion.

[0010] Preferably, the inner side of the cushion body is provided with an elastic cloth covering the movable massage head.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a foldable dual-purpose backrest cushion with two modes: massage mode and regular backrest mode. In massage mode, the inner side of the cushion body faces away from the seat back, and the two side wings bend inward to form a wrapping posture for the waist, achieving all-round support for the waist. At this time, the movable massage head moves back and forth or rotates under the control of the massage mechanism to achieve a kneading massage effect on the waist. When the massage function is not needed, the two side wings are bent outward, and the inner side of the cushion body is placed facing the seat back again. At this time, the movable massage head and the waist are respectively located on the inner and outer sides of the cushion body. In the non-massage state, the discomfort caused by the interactive massage head to the waist is completely avoided, and the wrapping support of the waist by the two side wings is achieved, effectively ensuring comfort. Users do not need to replace ordinary backrest cushions; one cushion can achieve the effect of two usage modes, which is cost-effective and highly practical. Attached Figure Description

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments. The content mentioned in the embodiments is not intended to limit the present invention.

[0018] like Figures 1 to 5 As shown, a foldable dual-purpose cushion includes a cushion body 1, a movable massage head 2 fixedly installed inside the cushion body 1, and a massage mechanism 3 for driving the movable massage head 2 to perform massage actions. Both sides of the cushion body 1 are provided with side wings 4 that can be folded back and forth relative to the cushion body 1. A flexible shaping member 5 is fixedly installed inside the cushion body 1, and the two ends of the flexible shaping member 5 extend into the two side wings 4 respectively.

[0019] In practical applications, the foldable dual-purpose backrest cushion has two modes: massage mode and regular backrest mode. In massage mode, the inner side of the cushion body 1 faces away from the seat back, and the two side wings 4 bend inward to form a wrapping posture for the waist, providing all-round support. At this time, the movable massage head 2 moves back and forth or rotates under the control of the massage mechanism 3, achieving a kneading massage effect on the waist. When the massage function is not needed, the two side wings 4 are bent outward, and the inner side of the cushion body 1 is placed facing the seat back again. At this time, the movable massage head 2 and the waist are located on the inner and outer sides of the cushion body 1, respectively. In the non-massage state, the discomfort caused by the interactive massage head to the waist is completely avoided, and the wrapping support of the waist by the two side wings 4 is still achieved, effectively ensuring comfort. Users do not need to replace ordinary backrest cushions; one cushion can achieve the effect of two usage modes, making it cost-effective and highly practical.

[0020] In this embodiment, mounting pieces 6 are fixedly provided at both ends of the bendable shaping part 5. The mounting pieces 6 are fixedly connected to the side wings 4, which facilitates the installation and fixing of the ends of the bendable shaping part 5 to the side wings 4. The assembly difficulty is low, the production cost is reduced, and the cost performance is high.

[0021] In this embodiment, the flexible shaping component 5 is a flexible metal hose or a fold-resistant gooseneck tube, which can not only realize multiple bends and repeated deformation transformations of the shaping component to extend its service life, but also facilitate shaping and fixing after folding. It is easy to operate and highly practical.

[0022] In this embodiment, the two side wings 4 are located at the lower edge and are used to wrap and support the waist of the human body on both sides, so as to prevent the cushion from shifting to the side during use and affecting the normal support function, thus providing a better user experience.

[0023] In this embodiment, a bend line is provided at the connection between the side wing 4 and the cushion body 1. The distance between the two bend lines is less than the width of the top of the cushion. The bend line is the fold line of the side wing 4 relative to the backrest body, which indicates the specific position of the side wing 4 when it is folded, making it convenient for the user to perform the folding operation. It is simple and practical.

[0024] In this embodiment, the inner side of the cushion body 1 is provided with an elastic cloth covering the movable massage head 2 to prevent hair, clothes or other foreign objects from getting into the movable massage head or the mechanism during the massage process, which could cause safety hazards or equipment damage, thus ensuring high safety.
