In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is：
This is used for the waist support of automotive seat, including base plate and scissor linkage and for the waist supporting to lumbar support
Plate, the lumbal branch fagging is located on base plate by scissor linkage, and the base plate is provided with for driving scissor linkage
The pushing motor of bottom two ends relative motion；The lumbal branch fagging is provided with for arch upward shell fragment or the spring to lumbar support
Pad, arch upward shell fragment or the spring pad are located at lumbal branch fagging side, and the scissor linkage is located at lumbal branch fagging opposite side.
Further, the lumbar support plate is plastic plate.
The lumbal branch fagging is provided with the ear mount with holes and trough of belt ear mount being connected for scissor linkage two ends.
The base plate is provided with slidable slide plate, and slide plate is located on the push rod of pushing motor, the scissor linkage
Bottom end is located on slide plate, and the scissor linkage bottom other end is located at and is located in the chute on base plate.
Relative two edges are provided with a pair and convex to form slide rail on the base plate, and slide plate is located in two projections.
The scissor linkage bottom other end is provided with T-shaped slide block, and the chute on base plate is adapted with T-shaped slide block.
The pushing motor is located at slide plate side, and limiting plate is provided with slide plate opposite side on base plate.
Compression spring is provided between the slide plate and limiting plate.
The compression spring is a pair, and the axis of push rod is located at the centre of the axis of a pair of compression springs.
The present invention compared with prior art, with advantages below：
The waist holder structure that this is used for automotive seat is reasonable in design, and by scissor linkage the motion of lumbal branch fagging is driven, long
Phase is hardly damaged using reliable and stable；Driven by compression spring and shell fragment has preferable pooling feature, to human body back
Damping of shocks, improves the comfortableness of backrest.
Description of the drawings
The content and the mark in figure expressed by each width accompanying drawing of this specification is briefly described below：
Fig. 1 is supporting structure schematic diagram of the present invention.
Fig. 2 is base arrangement schematic diagram of the present invention.
In figure：
1. lumbal branch fagging, the shell fragment that 2. arches upward, 3. ear mount with holes, 4. trough of belt ear mount, 5. connecting rod, 6. base plate, 7. pushing motor,
8. slide plate, 9. compression spring, 10. slide rail, 11. chutes.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, further details of is made to the specific embodiment of the present invention
Explanation.
As depicted in figs. 1 and 2, this is used for the waist support of automotive seat, including base plate 6 and scissor linkage and for right
The lumbal branch fagging 1 of lumbar support, wherein, lumbal branch fagging 1 is located on base plate 6 by scissor linkage, base plate 6 be provided with for
The pushing motor 7 of scissor linkage bottom two ends relative motion is driven, stretches to promote waist supporting by scissor linkage
Plate is moved.
Lumbal branch fagging 1 is provided with for arch upward shell fragment 2 or the spring pad to lumbar support, elastically deformable when back impacts
With pooling feature, comfortableness is improved.
Lumbal branch fagging 1 is provided with the ear mount with holes 3 and trough of belt ear mount 4 being connected for scissor linkage two ends.Arch upward bullet
Piece or spring pad are located at lumbal branch fagging side, and ear mount with holes and trough of belt ear mount are located at lumbal branch fagging opposite side, that is, arch upward shell fragment or
Spring pad is located at lumbal branch fagging side, and scissor linkage is located at lumbal branch fagging opposite side.Lumbal branch fagging is plastic plate, meets whole
Car lightweight requirements.
Base plate 6 is provided with slidable slide plate 8, and slide plate 8 is located on the push rod of pushing motor, relative two edges on base plate 6
It is provided with a pair and convexes to form slide rail 10, slide plate is located in two projections., the cunning of slide plate spacing to the direction of motion of slide plate by slide rail
Dynamic direction can only be along the axis direction of push rod.
Scissor linkage is two connecting rods being hinged by rotating shaft, and two connecting rod dimensions are identical, and rotating shaft is located at centre
At position；The bottom end of connecting rod 5 of scissor linkage is located on slide plate 8 by bearing pin, the connecting rod bottom of scissor linkage
The other end is located at and is located in the chute 11 on base plate 6, in chute 11 slidably.Preferably, scissor linkage bottom is another
End is provided with T-shaped slide block, and the chute on base plate is adapted with T-shaped slide block, and simple structure is reliable and stable.
Pushing motor 7 is located at slide plate side, and limiting plate is provided with slide plate opposite side on base plate.Set between slide plate and limiting plate
There is compression spring 9.Compression spring 9 is a pair, and the axis of push rod is located at the centre of the axis of a pair of compression springs.
Pushing motor works, and the push rod of pushing motor promotes slide plate, so as to drive scissor linkage bottom two ends opposite
Motion, scissor linkage retraction, lumbal branch fagging does not work.When pushing motor does not work, compression spring promotes skateboarding, from
And scissor linkage bottom two ends move toward one another is driven, scissor linkage drives lumbal branch fagging to stretch out, and people's waist is formed
Support.
In vehicle traveling, when people's waist impacts to lumbal branch fagging, damping buffering can be carried out by compression spring, improve seat
The comfortableness of backrest.And also can control motor and form self-locking, lumbal branch fagging and scissor linkage are in a fixed position,
Support Position of the different crowd to lumbal branch fagging is met, now by the shell fragment elastic deformation buffering that arches upward on lumbal branch fagging.
