There are two slide-and-guide slots 21 for the inner surface tool of outside plate 2.Specifically, two cards are set in the inner surface of the leg support outside plate 2
Item 22, each strip 22 surround to form the slide-and-guide slot 21 with the inner surface of leg support outside plate 2 respectively.
Refer to Fig. 3, Fig. 4, Fig. 6 and Fig. 7, the special rocker arm 5 altogether there are two, the structure of each special rocker arm 5 is identical,
Specifically, each special rocker arm 5 includes rotation section 53, and tool is there are two the deck 54 being oppositely arranged on the rotation section 53, and two
Gap is left between a deck 54, the outer end of two decks 54 is respectively provided with the lug boss 541 along the direction extension being located remotely from each other, when
Before two decks 54 are embedded on link block 31 after, can reliably /V be carried out by lug boss 541, make special rocker arm 5 can only
It is rotated relative to preceding link block 31.The both sides of rotation section 53 are respectively provided with the first cursor 55 and the second cursor 56, and first rotates
Between 55 and second cursor 56 of arm have angle so that special rocker arm 5 can coordinate the driving sat on basin 6 sliding slot 61 make its with
Slide-and-guide slot 21 is slidably matched, and leg support outside plate 2 is driven to rotate and store.It is formed and driven after the outer end bending of first cursor 55
The adaptable bending part 51 of dynamic sliding slot 61, the outer end of the second cursor 56 have lead 52, and the lead 52 insertion corresponds to
Slide-and-guide slot 21 in, and can be slided along slide-and-guide slot 21, the central axis of the lead 52 and turning for special rocker arm 5
Shaft line is parallel.
Fig. 2, Fig. 4 and Fig. 5 are referred to, loss of weight is equipped on the leg support mainboard 1, preceding link block 31 and rear link block 32
Slot on the premise of structural strength is ensured, can effectively reduce the weight for sitting basin leg support adjusting mechanism, meet light-weighted want
It asks.
Refer to Fig. 1~Fig. 6, it is a kind of with the automotive seats chair basin for sitting basin leg support adjusting mechanism, including sitting basin 6 and above-mentioned
Sit basin leg support adjusting mechanism.
The fixed seat 34 of the balladeur train 3, which is fixedly mounted on, sits on basin 6, sits on basin 6 and opens up there are two along the longitudinal direction at this
The balladeur train guide groove 62 of extension, there are two slide protrusions protruding upward for one end tool that link rod part 311 is connected with rear link block 32
312, two slide protrusions 312 are respectively slidably matched with a balladeur train guide groove 62, and balladeur train 3 is enable to move back and forth, and passes through cunning
The both ends of frame guide groove 312 define maximum sliding position, further substantially increase integrally-built reliability.
The motor 4 is mounted on the lower surface for sitting basin 6, and motor shaft 41 extends back along the lower surface for sitting basin 6.
The front end for sitting basin 6 has the driving sliding slot 61 identical with 5 quantity of special rocker arm, which slides 61 shape
It is adapted respectively with corresponding bending part 51, when leg support mainboard 1 skids off forward, leg support outside plate 2 can be in seat surface sleeve tension
Under the action of be flipped up, when leg support mainboard 1 is withdrawn backward, the special rocker arm 5 from 51 beginning of bending part insertion pair
In the driving sliding slot 61 answered, leg support outside plate 2 downwardly turns under the drive of special rocker arm 5.
Specifically, seat surface sleeve has certain ductility and elasticity, no matter is skidded off forward or leg in leg support mainboard 1
When support mainboard 1 slides rearward into, seat surface sleeve is in the state tightened, and seat surface sleeve not only persistently carries the thigh of driver and passenger
For effectively supporting, prevent to press from both sides the situation of meat, it is safe, and also seat surface sleeve can forward be skidded off in leg support mainboard 1
When, leg support outside plate 2 is pulled up by the tension of itself, it is flipped up and is in opening state, and then make leg support outside plate 2
Position between the thigh of driver and passenger and thigh and shank is provided effectively and comfortably supported;When leg support mainboard 1 backward
When slipping into, the tension of seat surface sleeve starts to reduce, and while the insertion of bending part 51 drives sliding slot 61, can drive special rocker arm 5
It rotates, so as to by special rocker arm 5 leg support outside plate 2 be driven to downwardly turn over, realizes the storage of leg support outside plate 2.
The course of work of the utility model is as follows:
When the drive motor shaft 41 of motor 4 rotates in one direction, link block 32 translates forward after motor shaft 41 drives, together
When, rear link block 32 drives guide rod 33 to be moved forward along fixed seat 34, and preceding link block 31 moves forward under the promotion of guide rod 33,
Finally move forward leg support mainboard 1, the forward movement of leg support mainboard 1 is skidded off while sit basin 6, is coated on leg support mainboard 1 and is sat
Seat surface sleeve tension on basin 6 constantly increases, and therefore, seat surface sleeve, which has, pulls up the active force of leg support outside plate 2, outside leg support
Plate 2 is flipped up certain angle under the pulling of seat surface sleeve.
When the drive motor shaft 41 of motor 4 rotates to another way, link block 32 translates backward after motor shaft 41 drives, together
When, rear link block 32 drives guide rod 33 to be moved backward along fixed seat 34, and preceding link block 31 moves backward under the pulling of guide rod 33,
Finally move backward leg support mainboard 1, leg support mainboard 1, which moves backward, to be slid back to while sit basin 6, is coated on leg support mainboard 1 and is sat
Seat surface sleeve tension on basin 6 constantly reduces, and when leg support mainboard 1 slides back to certain distance, bending part 51 starts embedded driving and slides
Slot 61 during continuous embedded driving sliding slot 61, drives special rocker arm 5 to rotate, while lead 52 is along slide-and-guide slot
21 slide, and leg support outside plate 2 is driven to downwardly turn over.
Finally it should be noted that foregoing description is only the preferred embodiment of the utility model, the common skill of this field
Art personnel on the premise of without prejudice to the utility model aims and claim, can make under the enlightenment of the utility model
Expression, such conversion are each fallen within the scope of protection of the utility model as multiple types.
