The fixing part 1 can fix the sofa top waist device on the sofa, so that the driving part 2 drives the linkage part 3 to adjust the distance between the top waist part 4 and the fixing part 1, thereby adjusting the inclination angle of the sofa.

The specific installation mode is as follows: the driving part 2 is fixedly arranged on the fixing part 1, and the driving part 2 is in transmission connection with the linkage part 3. It should be noted that, the driving member 2 may be fixed to the fixing member 1 by a threaded connection, welding, or the like, preferably by a threaded connection, and the threaded connection may be used to conveniently detach the driving member 2 from the fixing member 1.

In this embodiment, top waist part 4 detachably locates linkage part 3, top waist part 4 and linkage part 3 lug connection have simplified mounting structure greatly, and detachable relation of connection can be threaded connection simultaneously for it becomes very easy to dismantle top waist part 4, and easy operation saves user's equipment time in a large number, has brought pleasing use experience for the user.

As a further improvement of the above solution, the fixing member 1 includes a fixing frame 11 and a fixing plate 12, the driving member 2 is fixed to the fixing frame 11, the driving member 2 can stably output driving force, and the linking member 3 drives the waist ejecting member 4 to move, so as to adjust the position of the waist ejecting member 4.

The top waist part 4 comprises a connecting piece 41 and a top waist plate 42, the top waist plate 42 is directly connected with the backrest of the sofa, so that the strength is high, the safety of a user is ensured, but the top waist plate 42 is required to be connected with other parts, the rigidity is reduced by arranging a plurality of connecting holes on the top waist plate, the connecting piece 41 is arranged, the connecting piece 41 is fixedly connected with the top waist plate 42, the connecting piece 41 is connected with the linkage part 3, so that a few connecting ports are formed in the top waist plate 42, the rigidity is greatly increased, the transmission is not influenced, the structural design is reasonable, and the practicability is high.

Referring to fig. 2-4, the specific installation method is: the linkage part 3 is movably connected with the connecting piece 41, and the linkage part 3 is movably connected with the fixed frame 11.

Also, the top waist panel 42 may be deformed after a long time and thus needs to be replaced, and for this reason, the connecting member 41 is detachably connected to the top waist panel 42, which facilitates the replacement of the top waist panel 42.

In this embodiment, the number of the fixing plates 12 is two, and the fixing plates 12 are fixedly disposed at two ends of the fixing frame 11.

As a further improvement of the above solution, the linkage part 3 includes a first linkage rod 31 and a second linkage rod 32.

The first linkage rod 31 and the second linkage rod 32 are arranged in a staggered mode, and the middle of the first linkage rod 31 is hinged to the middle of the second linkage rod 32, so that linkage of the first linkage rod 31 and the second linkage rod 32 is achieved.

The specific motion process of the connection relation is as follows:

when the driving part 2 drives the first end of the first linkage rod 31 to be away from the driving part 2 along the length direction, the second end of the first linkage rod 31 pulls in the connecting piece 41 along the width direction, so that the connecting piece 41 is close to the driving part 2, and meanwhile, the second end of the second linkage rod 32 is away from the driving part 2 on the connecting piece 41 along the length direction.

When the driving part 2 drives the first end of the first linkage rod 31 to be close to the driving part 2 along the length direction, the second end of the first linkage rod 31 pushes out the connecting piece 41 along the width direction, so that the connecting piece 41 is far away from the driving part 2, and meanwhile, the second end of the second linkage rod 32 is far away from the driving part 2 on the connecting piece 41 along the length direction.

As a further improvement of the above scheme, the fixed frame 11 is provided with a first sliding groove 111, the connecting member 41 is provided with a second sliding groove 411, the first sliding groove 111 and the second sliding groove 411 are both provided with sliding members 5, the sliding member 5 of the first sliding groove 111 is fixedly connected with the output end of the driving part 2, the first end of the first linkage rod 31 is hinged with the sliding member 5 of the first sliding groove 111, and the second end of the second linkage rod 32 is hinged with the sliding member 5 of the second sliding groove 411.

In this embodiment, the first linkage rod 31 and the second linkage rod 32 are driven to move in the length direction by the sliding of the sliding member 5 in the chute, and the sliding may also be realized by arranging a sliding block to cooperate with the chute, which is not limited herein.

As a further improvement of the above solution, the driving member 2 is an electric cylinder or an electric push rod. Electric cylinder and electric putter all can realize direct output along length direction's power and displacement, and the control of being convenient for and precision are high, also can select voice coil motor as driving piece equally.

As a further improvement of the above, since the closest position of the driving member 2 to the lumbar support member 4 depends on the length of the slide groove during use, when the length of the slide groove is too long, there is a possibility that the driving member 2 may collide with the driving member 2, causing damage to the driving member 2.

Therefore, the fixing component 1 is further provided with a limiting component 112, the limiting component 112 is movably connected with the fixing frame 11, and the limiting component 112 is used for preventing the waist-supporting component 4 from approaching the driving component 2.

As a further improvement of the above solution, the fixing plate 12 includes a first plate 121 and a second plate 122, the first plate 121 is fixedly connected to the second plate 122, and by providing the two plates, the contact area with the sofa is increased, so that the fixing member 1 can be stably fixed to the sofa.

As a further improvement of the above solution, the first plate 121 is perpendicular to the second plate 122, the perpendicular arrangement can save most space, and at the same time, the first plate 121 is perpendicular to the second plate 122 only at a preferred angle, and the first plate 121 may have a certain inclination angle with respect to the second plate 122 as long as the connection function is satisfied.
