Support, alleviate the discomfort for taking lower leg for a long time, the comfort for improving seat is very helpful, the prior art
Leg support of seat system mostly uses greatly gas spring structure, and multi link adds screw structure.Not only structure is complicated, and production cost is high, quality
It is difficult to ensure.On the other hand, automobile, train and ship seat, typically no leg support at present, or there is leg support to be also not electronic control
System or an only section about 300mm long, practical value is low, and function is simple, also only allow passenger's being comfortable in short-term, and
Passenger cannot be allowed to be in comfort conditions for a long time.
Such as China Patent No. ZL 201420426123.7, the reality of entitled " regulating mechanism before and after vehicle seat leg support "
With new patent, a kind of adjusting mechanism for leg support of seat is disclosed, including the sliding block being fixedly linked on seat support basin, leg support lid
Plate is located at the top of sliding block, and between leg support cover board and sliding block be equipped with unlock when make leg support cover board along the longitudinal direction relatively under
Make leg support cover board and the relatively-stationary unlock of sliding block and lockable mechanism when sliding block sliding, locking, the starting of unlock is by bracing wire control
System.The patent is adjusted using sliding block, and operating is then this structure using bracing wire and sliding block by bracing wire and link mechanism,
Neither terse and unreliable, poor for applicability, effect is unsatisfactory.
For another example publication No. is the Chinese invention patent of CN103029604A, discloses a kind of seat and its leg support adjusts dress
It sets, which mainly includes angle adjustor and link mechanism, wherein the fixing piece of angle adjustor is used for and the seat
Fixing piece connection, the power input lever of the link mechanism are connected with the rotation output of the angle adjustor, the link mechanism
Power output rod for being connected with leg support, switched between stretching state and retracted state with adjusting the posture of the leg support.
But the part size that the leg support is used to carry human leg is fixed, and can not be adjusted, so that the support model of leg support device
It encloses limited, reduces its applicability and comfort to a certain extent.
In view of above-mentioned technical problem of the existing technology, it is necessary to provide the new leg support of seat of one kind to overcome the above institute
The technical issues of description.
Utility model content:
