Description

TECHNICAL FIELD

[0001] The present application relates to a massage chair back cushion driven manually or electrically. BACKGROUND

[0002] The massage chair in the prior art comprises a backrest for users to lean on when using the waist, back, shoulder, neck and head. The existing massage backrest usually comprises a backrest frame and a massage movement core arranged on the backrest frame, and the massage movement core is provided with massage heads. The massage heads of the massage movement core can perform targeted massage on different parts of the user, thereby achieving the effects of relieving fatigue and relaxing muscles.

[0003] The backrest of the conventional massage chair is designed with the massage heads of the massage movement core protruding relative to the leaning surface of the backrest in order to improve the massage effect on specific parts of the body. When the user leans on the massage chair as a daily seat, especially as a daily office chair or sofa chair, the back is pressed by the massage heads, which causes a sense of strangeness and discomfort, and seriously affects the leaning use in the non-massage state.

[0004] At present, some massage chairs have a movement structure design of the massage movement core on the backrest, which can move forward and backward. When the massage function is needed, the massage movement core is driven to move forward by a driving mechanism, so that the massage heads protrude forward along the leaning surface of the backrest. When the massage function is not needed, the massage movement core is driven to move backward by the driving mechanism, so that the massage heads are retracted into the inside of the backrest to avoid contact with the human body. The existing design scheme increases the structural complexity and manufacturing cost of the massage movement core. In addition, when the massage heads are retracted, the corresponding position of the front part of the backrest will be concave, which affects the leaning effect. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a massage chair back cushion driven manually or electrically, which can shield or not shield the massage heads of the massage movement core by moving the position of the back cushion body relative to the backrest frame, thereby improving the comfort in the non-massage use.

[0006] In order to achieve the above object, the application discloses a manually driven or electrically driven massage chair cushion, which comprises a backrest and a cushion body. The backrest comprises a front part, a rear part and a top part. The front part of the backrest is used for the user's back to lean against. At least one guide component is arranged on the backrest. The guide component comprises a front segment arranged longitudinally on the front part of the backrest, a middle segment arranged on the top part of the backrest and a rear segment arranged on the rear part of the backrest. The cushion body is connected with the guide component. The guide component is used for limiting the movement track of the cushion body, so that the cushion body can move along the front part, the top part and the rear part of the backrest. The backrest comprises a cavity. A massage core is arranged in the cavity. A convex massage part is formed on the position corresponding to the massage core on the front part of the backrest. The massage part is arranged at a specific position of the backrest, so as to massage the user's shoulder, neck, waist, back or head. When the massage part is used, the cushion body can be adjusted to other positions to avoid shielding the massage part, so that the massage part can press on the human body, and the cushion body can also be used as a pillow to lean against other parts of the human body. The cushion body can also be moved to the rear part of the backrest to be hidden, so as to avoid the loss of the cushion body. When the massage is not needed, the cushion body can be moved along the guide component to the front part of the massage part to shield the massage part, so that the user will not feel conspicuous when normally sitting on the backrest due to the convex massage part. The cushion body is arranged outside the massage part to be used by the user to lean against, so as to improve the comfort during use. The guide component is arranged on both sides of the backrest. The massage part is arranged between the two guide components. The two guide components are arranged on both sides of the backrest, so as to avoid interference with the massage part and improve the stability of the movement of the cushion body. The backrest is provided with grooves on both sides. The guide component is arranged in the groove. The depth of the groove is greater than the height of the guide component, so that the guide component is not exposed outside and can be better protected, and the appearance can also be improved. The middle part of the front part of the backrest is recessed relative to both sides. When normally sitting on the backrest, the user can feel more comfortable. The massage part is arranged in the recessed part of the front part of the backrest. On one hand, the massage part will not be excessively convex. On the other hand, the cushion body can also be partially embedded in the recessed part, so as to improve the comfort and the appearance.

[0007] Further, the guide component comprises two side walls, a bottom wall connected between the inner ends of the two side walls, two top walls, and a cavity formed around the two side walls, the bottom wall, and the two top walls, one side of the two top walls is connected with the outer ends of the two side walls respectively, and the other side of the two top walls is spaced apart to form a through slot. The side of the cushion body corresponding to the backrest is provided with a pulley assembly for sliding connection with the guide component. The pulley assembly comprises a wheel seat, a pulley, and a connecting ring. The connecting ring is arranged at one end of the wheel seat and is connected with the cushion body. The pulley is arranged at the other end of the wheel seat and is rolled with the inner wall of the cavity. The wheel seat is arranged between the inner and outer sides of the guide component along the through slot. The top wall and the pulley are limited to cooperate, which can prevent the pulley from being pulled out of the through slot, and ensure the reliable connection between the cushion body and the backrest. The end of the guide component is provided with an opening, and the pulley assembly can be disassembled along the opening of the end of the guide component.

[0008] Further, the cushion body comprises an inner core and an outer cover wrapped outside the inner core. The inner core is a sponge, and the outer cover is sewn from cloth or leather, thereby improving the comfort of the cushion body when used.

[0009] Further, the cushion body comprises a first protruding part and a second protruding part connected integrally. The first protruding part and the second protruding part are formed with grooves. When the cushion body is completely slid to the front part of the backrest, the first protruding part and the second protruding part are located close to the top and the bottom of the backrest respectively. The first protruding part can be used for the head, shoulder, back, and other parts of the user to lean on, and the second protruding part can be used for the waist of the user to lean on, thereby improving the comfort during use. The grooves make the appearance of the cushion body more beautiful.

[0010] As another preferred solution, the guide component is a transmission belt, and the backrest cavity is provided with a guide wheel for transmission with the transmission belt. At least two guide wheels are arranged on both sides of the backrest cavity to be connected with the transmission belt. The guide wheels on both sides of the backrest are connected in transmission with the guide components, which enables the transmission belts on both sides of the backrest to move synchronously. One of the guide wheels is connected with a driving mechanism, which can drive the guide components on both sides of the backrest to move synchronously. The two sides of the cushion body are fixed at specific positions of the transmission belt by elastic ropes or hooks. The driving mechanism drives the guide wheel to rotate and further drives the transmission belt to move. When the transmission belt moves, it can drive the cushion body to move along the front part, the top part, and the rear part of the backrest.

[0011] Further, the driving mechanism comprises a speed reducer arranged in the backrest cavity, and the output shaft of the speed reducer is connected in transmission with one of the guide wheels. The driving mechanism drives the cushion body to move by electricity, which is more labor-saving. The driving mechanism can also be connected with the control center of the massage chair to realize functions such as automatic homing when the massage chair is turned off, automatic switching of use modes, and the like.

[0012] Further, the driving mechanism comprises a hand wheel arranged on one side of the back cushion body, and the hand wheel is in transmission connection with one of the guide wheels. The guide wheels and the transmission belt can be driven to move through the hand wheel, and the back cushion body can be driven to move through the rotation of the driving hand wheel.

[0013] The back cushion body can be moved along the track defined by the guide component relative to the back frame, so that the position of the back cushion body can be adjusted. The user can adjust the position of the back cushion body according to the use requirement. When the massage function is not used, the back cushion body can be moved to the position corresponding to the massage part of the massage core, so that the back cushion body can shield the massage part, and the comfort during leaning can be improved. When the massage is needed, the back cushion body can also be moved to the back of the back frame, so that the massage part can normally massage the user. BRIEF DESCRIPTION OF DRAWINGS
