Description

Technical Field

[0001] The invention relates to the technical field of detachable back cushions used in combination with seats, in particular to a foldable dual-purpose back cushion. Background Art

[0002] The massage cushion is an additional cushion placed between the seat back and the waist. On the one hand, it can make up for the deficiency that the backrest shape cannot fully fit the waist. On the other hand, a massage mechanism is added to massage the waist during use, achieving the technical effect of adding a massage function to a conventional seat, satisfying this demand of many consumers.

[0003] However, in actual application, it is found that after the massage cushion with massage function is installed on an ordinary seat, there is only one massage mode, that is, when massage is needed, turning on the massage device can achieve massage of the waist. When the user needs to rest and stop the massage, although the massage function is turned off, the massage device still presses against the waist, causing a serious diaphragm feeling, seriously affecting the user experience. After removing the entire massage cushion, the overall support of the waist cannot be achieved, and an additional ordinary cushion needs to be replaced before use. The use cost is high and the defects are obvious. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a foldable dual-purpose cushion which can be used as a massage cushion and can be converted into a common cushion by turning it over and placing it.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: a foldable dual-purpose cushion, comprising a cushion body, a movable massage head fixedly mounted on the inner side of the cushion body, and a massage movement for driving the movable massage head to perform massage movements, wherein both edges of the cushion body are provided with side wings that can be folded forward and backward relative to the cushion body, and a curved positioning piece is fixedly mounted inside the cushion body, and both ends of the curved positioning piece extend into the two side wings respectively.

[0006] Preferably, the middle section of the curved positioning member is fixedly connected to the outer shell of the massage movement.

[0007] Preferably, mounting plates are fixedly provided at both ends of the curved positioning member, and the mounting plates are fixedly connected to the side wings.

[0008] Preferably, the bending positioning member is a bending-resistant metal hose or a folding-resistant gooseneck tube.

[0009] In another preferred embodiment, the bending positioning member includes a middle supporting section and two bending sections hinged to both ends of the middle supporting section through a damping shaft, and the mounting plate is fixed to the outer end of the bending section.

[0010] Preferably, the middle supporting section and the two bending sections are both made of profiled aluminum bars.

[0011] Preferably, the two side wings are located at the lower part of the edge.

[0012] Preferably, a bending line is provided at the connection between the side wing and the cushion body, and the distance between the two bending lines is smaller than the width of the top of the cushion.

[0013] Preferably, an elastic cloth covering the movable massage head is provided on the inner side of the cushion body.

[0014] The beneficial effect of the present invention is that the present invention provides a foldable dual-purpose cushion, which has two modes, a massage mode and a conventional cushion mode. In the massage mode, the inner side of the cushion body is placed back to the seat back, and the two side wings are bent inward to form a wrapping posture for the human waist to achieve all-round support for the waist. At this time, the movable massage head moves back and forth or rotates to massage under the control of the massage movement 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 repositioned toward the seat back. At this time, the movable massage head and the human waist are respectively located on the inner and outer sides of the cushion body. In the non-massage state, the diaphragm feeling of the interactive massage head on the human waist is completely avoided, and the wrapping support feeling of the two side wings on the waist is also achieved, and the comfort is effectively guaranteed. The user does not need to replace the ordinary cushion, and the effect of two usage modes can be achieved with one cushion, which is cost-effective and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments, and the contents mentioned in the implementation modes are not intended to limit the present invention.

[0022] like Figures 1 to 5 The figure shows a first embodiment of a foldable dual-purpose cushion, comprising a cushion body 1, a movable massage head 2 fixedly mounted on the inner side of the cushion body 1, and a massage movement 3 for driving the movable massage head 2 to perform massage movements. Both edges of the cushion body 1 are provided with side wings 4 that can be folded forward and backward relative to the cushion body 1. A curved positioning piece 5 is fixedly mounted in the cushion body 1, and both ends of the curved positioning piece 5 extend into the two side wings 4 respectively.

[0023] In actual application, the foldable dual-purpose cushion has two modes, massage mode and conventional cushion mode. In massage mode, the inner side of the cushion body 1 is placed back to the seat back, and the two side wings 4 are bent inward to form a wrapping posture for the human waist to achieve all-round support for the waist. At this time, the movable massage head 2 moves back and forth or rotates to massage under the control of the massage movement 3 to achieve 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 repositioned toward the seat back. At this time, the movable massage head 2 and the human waist are located on the inner and outer sides of the cushion body 1 respectively. In the non-massage state, the diaphragm feeling of the interactive massage head on the human waist is completely avoided, and the wrapping support feeling of the two side wings 4 on the waist is also achieved, and the comfort is effectively guaranteed. The user does not need to replace the ordinary cushion, and the use of one cushion can achieve the effects of two usage modes, which is cost-effective and practical.

[0024] In this embodiment, the middle section of the curved positioning member 5 is fixedly connected to the outer shell of the massage mechanism 3, which improves the structural strength of the curved positioning member 5 inside the cushion body 1 and provides better stability.

[0025] In this embodiment, mounting plates 6 are fixedly provided at both ends of the bending positioning member 5, and the mounting plates 6 are fixedly connected to the side wings 4, which facilitates the installation and fixation of the ends of the bending positioning member 5 to the side wings 4, reduces the difficulty of assembly, reduces the production cost, and has a high cost performance.

[0026] In this embodiment, the bending positioning member 5 is a bend-resistant metal hose or a fold-resistant gooseneck tube, which can not only realize multiple bending and repeated deformation transformation of the shaping member to extend the service life, but also facilitate shaping and fixation after folding, and is easy to operate and highly practical.

[0027] In this embodiment, the two side wings 4 are located at the lower part of the edge, and are used to wrap and support both sides of the waist of the human body, so as to prevent the cushion from shifting sideways during use and affecting the normal supporting function, and provide a better user experience.

[0028] In this embodiment, a bending line is provided at the connection between the side wing 4 and the cushion body 1. The distance between the two bending lines is less than the width of the top of the cushion. The position of the bending line is the folding line of the side wing 4 relative to the backrest body, which indicates the specific position of the side wing 4 when folding for the user, facilitates the user to perform the folding operation, and is simple and practical.

[0029] In this embodiment, an elastic cloth covering the movable massage head 2 is provided on the inner side of the cushion body 1 to prevent hair, clothes or other foreign objects from entering the movable massage head or the movement during the massage process, thereby preventing potential safety hazards or equipment damage, thereby achieving high safety.

[0030] like Figure 6 The second embodiment of a foldable dual-purpose cushion is shown, which is different from the first embodiment described above in that: the curved positioning member 5 includes a middle support section 51 and two bending sections 52 hinged to the two ends of the middle support section 51 through a damping shaft, and the mounting piece 6 is fixed to the outer end of the bending section 52. By utilizing the damping characteristics of the damping shaft, the bending section 52 can be fixed at any angle relative to the middle support section 51, and the bending angle of the side wing 4 can be adjusted as needed, making the structure more stable and reliable. The middle support section 51 and the two bending sections 52 are made of aluminum profiles, which have the advantages of high structural strength, high tolerance and lightness, and are more practical.
