Using drive mechanism as above, can realize to something or somebody to fall back on units by the motor of small volume and simple drive mechanism
Angular adjustment.
With regard to the installation of adjusting means, the present invention further preferably adopts following manner：The first crossbeam is along level side
To extension, first support is provided with the first crossbeam, the first support is configured to from the first crossbeam prolong upward
Stretch, for installing the motor and first drive mechanism；The second cross beam is the U-shaped prominent to seat rear,
Second support is provided with the second cross beam, the second support extends from the second cross beam to the front of the seat so that
First pivot axis are left in other words in one end deviation of the second support；One end of the connecting rod with described second
The end of frame is connected in articulated manner.It is so designed that the space mounting adjusting means made full use of in seat, and really
Protect the regulation arm of force to something or somebody to fall back on frameworks.
Design with regard to the stroke of adjusting means, the present invention is preferably arranged to the stroke of its first drive mechanism to make institute
Stating the angular range that something or somebody to fall back on frameworks are rotated relative to the back frame is within 60 degree, and the further preferred angle model
Enclose within 35 degree.By the slewing area for reasonably arranging something or somebody to fall back on frameworks so as to meet human engineering, it can be ensured that something or somebody to fall back on
Comfortableness and safety.
In backrest module of the invention, backrest unit and something or somebody to fall back on units are made up of respectively all-metal pipe fitting.This makes
Obtaining can effectively improve the productivity ratio of backrest finished product, and be conducive to designing the backrest style of succinct fashion.
According to second aspect, the present invention also provides a kind of seat, and the seat includes portions and aforesaid including backrest
The backrest module of unit and something or somebody to fall back on units, the something or somebody to fall back on units are arranged in articulated manner on backrest unit.According to the present invention
Seat allow user easily operate to adjust angle of the something or somebody to fall back on units relative to backrest unit.
Description of the drawings
Describe the preferred embodiments of the present invention in detail with reference to the accompanying drawings, wherein：
Fig. 1 is the present invention including backrest unit and the front view of the backrest module of something or somebody to fall back on units；
Fig. 2 is the side view of the backrest module shown in Fig. 1；And
Fig. 3 is the axonometric chart of the backrest module shown in Fig. 1.
Specific embodiment
Fig. 1 show the present invention including backrest unit and the front view of the backrest module of something or somebody to fall back on units, the backrest module
Including substantially rectangular back frame 10 and the substantially rectangular something or somebody to fall back on frameworks 20 being attached thereto, as illustrated, seat back frame
The upper end of frame 10 is connected by the first articulated joint 31 with the lower end of something or somebody to fall back on frameworks 20 with the second articulated joint 32.Further such as
Shown in Fig. 2, the first articulated joint 31 and the second articulated joint 32 have the first common pivot axis, so that something or somebody to fall back on frameworks
20 can within the specific limits rotate around first pivot axis relative to back frame 10, and then adjust the position of something or somebody to fall back on units
Put and/or angle.
In order to allow user from main regulation something or somebody to fall back on unit, according to the present invention, back frame 10 and something or somebody to fall back on frameworks 20 it
Between be provided with adjusting means 40, can realize rotation of the something or somebody to fall back on units relative to backrest unit by means of the adjusting means 40.
Adjusting means 40 can include motor 41, the first drive mechanism 42 and the second drive mechanism, second driver
Structure is in the present embodiment connecting rod 43.Be according to the basic principle of operation of the adjusting means 40 of the present embodiment, motor 41 it is defeated
The rotary motion of shaft is converted into linear movement by the first drive mechanism 42, so as to drivening rod 43 is realized pushing and pulling
Make.
According to the present invention, adjusting means 40 is preferably mounted between back frame 10 and something or somebody to fall back on frameworks 20：
As shown in Figures 1 to 3, preferably it is provided with first crossbeam 11 in a welding manner on back frame 10, and in the first crossbeam
First support 12 is set on 11, and the combination of the drive mechanism 42 of motor 41 and first may be mounted in the first support 12；This
Outward, second cross beam 21 is provided with something or somebody to fall back on frameworks 20, and second support 22 is set on the second cross beam, the one of connecting rod 43
End is connected with the first drive mechanism 42, and the other end is then hinged on the end of the second support 22.
According to the present invention, if the pivot center that the pin joint of connecting rod 43 and second support 22 is located is defined as into the second pivot
Axis, then produce the turning moment for surrounding the first pivot axis, the second pivot in order to ensure connecting rod 43 can be directed to something or somebody to fall back on frameworks 20
Shaft axis should keep parallel with the first pivot axis and misaligned, that is to say, that the pin joint of connecting rod 43 and second support 22 should
This leaves the segment distance of the first pivot axis one (i.e. the arm of force).
First drive mechanism 42 of the invention can be adapted to for rotary motion to be changed into linear movement using any
Drive mechanism, including but not limited to bevel gear mechanism, worm-and-wheel gear, pinion and rack, nut screw mechanism etc.
One of or their appropriate combination；Also, the axis of motor 41 can it is parallel with the length direction of connecting rod 43,
Vertically or into other suitable angles.In view of can be art technology by the drive mechanism that rotary motion is changed into linear movement
Personnel are of the invention to instruct what is be readily apparent that, will not be described here.
In general, user is required to adjust the something or somebody to fall back on of seat or sofa in certain comfortable and safe scope.
According to the present invention, the possible angle scope of something or somebody to fall back on units can be into 60 in the position alignd with backrest unit and with backrest unit
Between degree, preferably 35 degree of position.That is, from something or somebody to fall back on frameworks 20 and back frame 10 are in conplane position, leaning on
The scope that head framework 20 is rotated forward within 60 degree, within preferably 35 degree is most preferred slewing area.The present invention is adjusted in design
This angular range is taken into account during the stroke of regulating device 40, and by the first drive mechanism and the second drive mechanism
Parameters Optimal Design, the regulation angle of something or somebody to fall back on frameworks is limited in the range of 60 degree as above, preferably 35 degree of model
In enclosing.
In the present invention, it is preferred to first support 12 is arranged to from first crossbeam 11 to extend upward, it is undue thus to avoid
Take sofa or the space in front and back in seat and avoid causing potential safety hazard to user.Second cross beam 21 can be preferably provided with
For rearward prominent U-shaped, thus form an installing space in front of it, and can by second support 22 be arranged to from this
Two crossbeams 21 extend forward, so on the one hand make use of the installing space, on the other hand avoid excessively taking the space at rear.
According to the present invention, there is provided a kind of seat, such as sofa, it includes portions and aforesaid backrest module.Seat is leaned on
The back of the body multiple springs for may include backrest unit and being connected with the backrest unit, may also include various implants and flexibility
