Specific embodiment
Below in conjunction with the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
Embodiment: as shown in Figure 1-3, the regulating mechanism of a kind of head rest and Lumbar, including fixed frame 10,20 and of movable support
Driving device 30, head rest portion 21 of the movable support 20 including portion disposed thereon and the Lumbar portion 22 positioned at its underpart, it is described
Movable support 20 is rotationally connected on the fixed frame 10, and the driving device 30 is connected to movable support and fixation
Frame, and movable support 20 can be driven to rotate around fixed frame 10.The fixed frame 10 is including a cross bar 11 and is set to cross bar two
Hold and perpendicular to its two vertical bars 12, the movable support 20 further includes two companies for being connected to head rest portion 21 and Lumbar portion 22
Extension bar 23, the head rest portion 21 and Lumbar portion 22 are parallel to each other, described two connecting rods 23 be parallel to each other and be located at head rest portion and
The two sides in Lumbar portion.Movable support 20 in the utility model is mutually interconnected by head rest portion 21, Lumbar portion 22 and two connecting rods 23
Composition is connect, wherein head rest portion and Lumbar portion are parallel to each other, two connecting rods are parallel, connecting rod and head rest portion are perpendicular, and head rest
Portion passes through shaft and activity in the lower part of movable support, the vertical bar 12 of 10 two sides of fixed frame in the top of movable support, Lumbar portion
The connecting rod 23 of bracket is rotatablely connected, and driving device 30 is preferably the push-rod electric machine with unilateral thrust, the push-rod electric machine
11 hinge of cross bar at base end and the fixed frame 10, the push rod of push-rod electric machine and 22 hinge of Lumbar portion, work as push-rod electric machine
When driving its push rod that Lumbar portion 22 is pushed to move upwards, Lumbar portion is protruded outward, and the waist of user is resisted against, according to user
Use habit, movable support can be made to form different angles from fixed frame, in the process, human body tends to lie down；When pushing away
Moved when bar is retracted push-rod electric machine, under 22 phase of Lumbar portion, at the same time, using lever principle and the distinctive arc of connecting rod or
Bevel structure, head rest portion 21 will suitably move upwards, and in the process, human body tends to sitting, and head rest portion is just met for human body
The dependence on head.The utility model is made using the position that a driving device can adjust Lumbar portion and head rest portion simultaneously with meeting
The different demands of user enormously simplify original structure, easy to use, and there is the design for meeting ergonomics to improve
The usage comfort of user can widely apply to the functional thing to sit on such as chair, sofa.
As shown in Figure 1, being rotatablely connected between the fixed frame 10 and movable support 20 by shaft 24.Specifically, institute
The connecting rod 23 of the vertical bar 12 and the movable support of stating fixed frame is rotatablely connected by shaft 24.As shown in Fig. 2, the connection
Bar 23 includes the inclined board for being connected to head rest portion and the declined board for being connected to Lumbar portion, the folder between the inclined board and declined board
Angle is 145~165 °.The connecting rod 23 is integrally formed part, and using face is inclined-plane or curved surface, for example, by inclined board and
Declined board composition, therefore head rest portion and Lumbar portion are always in different planes, and Lumbar portion protrudes from head rest portion.Because even
Extension bar special shape thus, so when driving device pushes Lumbar portion to be moved upwardly or downwardly, according to lever principle head rest portion
It moves, and can reach so that head rest portion and Lumbar portion generate rotation angle identical with similar product in the opposite direction
When, the stroke of driving device reduces the function of half, energy saving and easy to use.
As shown in Figure 1, the driving device 30 is the push-rod electric machine with unilateral thrust, the base end of the push-rod electric machine
With 11 hinge of cross bar of the fixed frame 10, the push rod of push-rod electric machine and 22 hinge of Lumbar portion.The cross bar of the fixed frame
11 is parallel with the Lumbar portion 22, and the push-rod electric machine and the two are substantially vertical.It is pushed away in this way, advantageously reducing in the process of running
The stroke of push rod in bar motor.
It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the premise utility,
Various modifications and improvements can be made, and these are all within the protection scope of the present invention.Therefore, the utility model patent
The scope of protection shall be subject to the appended claims.
