And the buffer washer 13, the first sealing ring and the fixing bracket 16 are used for rotatably fixing the fixing seat 11 on the first pipeline connecting piece 9. The two sides of the fixed bracket 16 are provided with a first abutting projection and a second abutting projection which abut on the first pipeline connecting piece 9 and the fixed seat 11 respectively, so that the axial movement of the two is limited. And, the airtight effect between the fixing seat 11 and the first pipe connection member 9 can be ensured by the cushion gasket 13 and the first sealing member 14.

It will be appreciated that the first seal 14 is a sealing gasket and the second seal 15 is an O-ring seal.

Example II,

As shown in fig. 6 and 7, the present invention provides a massage apparatus including an air bag according to any one of the above embodiments.

Preferably, as shown in fig. 6 and 7, on the basis of the above-mentioned embodiments, in an alternative embodiment of the present invention,

it comprises a drive means 24, a massage member 23 and an air bag body 1. The driving device 24 serves as a power source. The massage member 23 is rotated by the driving device 24 to perform a massage operation. The bag body 1 transmits the power of the driving device 24 to the massage member 23. Wherein the airbag body 1 is connected between the driving device 24 and the massage member 23.

Specifically, as shown in the drawings, the bag body 1 is configured to be capable of being elongated or shortened in a set direction so that the massage member 23 approaches or moves away from the user, respectively. And the bag body 1 is configured to transmit power to the massage member 23 in an inflated state after being inflated. Preferably, the bag body 1 is configured as a multilayer bag.

As can be appreciated, the massage mechanism is mounted on the chair, and when massage is not needed, the comfort of the chair can be ensured only by keeping the surface of the chair flat; when massage is needed, the massage head needs to enable the surface of the chair to be protruded so as to be pressed against the human body (particularly against the back of the human body from the chair back), and then certain compression can be formed on the human body for massage.

In the present embodiment, the massage member 23 is driven away from or close to the driving device 24 by the air bag, not only enabling the massage mechanism to be switched between the operating state and the housed state. Moreover, the massage can be performed only by arranging the opening with the size almost the same as that of the massage mechanism on the seat.

It will be appreciated that the cross-sectional area of the massaging mechanism is substantially smaller than the drive means 24, so that only a small opening in the sponge of the chair is required to achieve the massaging function. The chair has the massage function, and meanwhile, the chair still has better comfort when the massage mechanism does not work.

Further, the rotational power of the driving device 24 is transmitted to the massage member 23 by the air bag, so that the distance and angle between the massage member 23 and the driving device 24 can be changed within a certain range. The massage angle of the massage member 23 can be adaptively changed within a certain range, thereby better adapting to the body surface of the user and obtaining a more comfortable massage effect.

It should be noted that the massage mechanism of the present invention is not limited to be used in a car comfort system (including a car seat), but is also applicable to various massage chairs or various massagers, and the application of the massage mechanism of the present invention is not limited in any way.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
