Description
Technical field
The utility model relates to a kind of adjusting mechanism for automobile seat, relates in particular to a kind of automotive seat leg holder regulating mechanism.
Background technology
Along with the fast development of automotive technology, people require more and more higher to the travelling comfort of automobile, and as the agent structure of carrying passenger, the function of seat is more and more subject to people's attention.
Because passenger's leg is long different, same seat is different to different passengers' thigh support degree, and at present traditional Chinese chair is that average leg length with people designs mostly, this just makes the people who those is departed to average leg length that good travelling comfort can not be provided, people design leg support mechanism are installed on the seat thus, occupant leg is provided to extra support, but leg support mechanism of the prior art needs while opening to stretch before release defensive position trend, this is very not convenient during in driving condition at chaufeur, and existing leg support mechanism generally only has one grade or two grades of adjustings, regulate span interval large, also cause the traveling comfort of leg support mechanism poor.
Chinese utility model patent CN201030807Y discloses a kind of automotive seat adjustable leg holder system, and this system comprises upper and lower slide rail, which is provided with a plurality of groove teeth; Attaching parts, comprises pressure head part and locking shaft, and described pressure head part is fixedly connected with upper slide rail by a rotating shaft, and locking shaft is stuck in a groove tooth.Adopt this system, when the holder of needs adjusting seat leg, thereby press down pressure head part and drive locking shaft upward movement, the groove tooth of locking shaft and glidepath is thrown off and release, now whole upper slide rail just can always be shaped as relative motion with seat cushion framework, locking shaft can be at any one groove tooth position and glidepath locking, thereby has realized the front and back regulatory function of leg holder.Many gears that above-mentioned automotive seat adjustable leg holder system has realized leg support mechanism regulate, but it still needs the leg holder that manually stretches after release, is not easy to use when driving condition.
Utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of automotive seat leg holder regulating mechanism, and its many gears that can realize leg holder regulate, and can automatically extend after leg holder release, have good practicality.
For achieving the above object, these automotive seat leg holder regulating mechanism comprises the seat basin main body being connected with cushion frame, and the leg support plate in the present basin main body of sliding block joint, between present basin main body and leg support plate, be provided with the different parts of the present basin main body of described leg support plate is entered to line-locked lockable mechanism, and open described lockable mechanism so that the leg support plate release mechanism that seat basin main body is slided before and after carrying out relatively, between present basin main body and leg support plate, be also provided with springing, described springing is when lockable mechanism is opened, driving leg support plate is to make it have the motion forward of relative seat basin main body.Adopt such scheme, utilize lockable mechanism the different parts of the present basin main body of leg support plate to be locked to many gears adjustings that just can realize leg support mechanism, when utilizing release mechanism to open lockable mechanism under the effect of springing, the driven relative seat basin main body of leg support plate travels forward automatically, thereby has realized the automatic elongation after leg holder release.
As the restriction to aforesaid way, described lockable mechanism comprises a plurality of lock grooves that arrange on present basin main body and leg support plate, and rotate and to be arranged on leg support plate, to drag lock groove on panel to carry out the locking rod of lock fit with described seat basin main body and leg, on locking rod, be provided with at least one and stretch into described lock groove to enter line-locked locking pawl.When making a basin main body, align with the lock groove on leg support plate, locking pawl on locking rod stretches in the lock groove of alignment, just can be by leg support plate together with the engaging of seat basin main body, thereby realize the locking to leg support plate, utilize lock groove in leg support plate and seat basin main body in the different parts engaging of aliging, just can realize many gears of leg support plate are regulated to locking.
As the restriction to aforesaid way, at locking rod, be provided with leg support plate with one end of leg holder panel hinged match, the rotation of locking rod is carried out to spacing rotary spacing piece.Just can avoid thus the interference between that the double swerve of locking rod and inordinate rotation cause and miscellaneous part.
As the restriction to aforesaid way, described release mechanism comprises that rotation is arranged on the mechanism body on leg support plate, be connected in the unlock button of mechanism body one end, and the release pressing plate that is arranged on the mechanism body other end of relative unlock button, described release pressing plate is conflicted and is coordinated with locking rod, and when capable of being unlocked by pressing button, drive release press plate rotary, to drive described locking rod to have, make the motion of the locking pawl disengaging lock groove on it.Capable of being unlocked by pressing button makes progress when release, because unlock button and release pressing plate are connected to the relative two ends of mechanism body, just can make release pressing plate there is downward rotation, release pressing plate is conflicted and is coordinated with locking rod, just can drive locking rod to rotate together, thereby the locking pawl on locking rod is spun off from lock groove, realized the release to leg support plate and seat basin main body.
As the restriction to aforesaid way, at locking rod, near one end of limiting stopper, be provided with releasing claw, described release pressing plate is conflicted and is coordinated with releasing claw.
As the improvement to aforesaid way, on described lockable mechanism and release mechanism, be respectively equipped with the elastic position rebounding device that loses while pressing, lockable mechanism and release mechanism are resetted respectively at unlock button.Like this, when capable of being unlocked by pressing button makes after leg support plate and the release of seat basin main body, if unclamp unlock button under the effect of elastic position rebounding device, release mechanism and lockable mechanism return, thereby can make the locking pawl on locking rod automatically stretch into leg support plate with a lock groove that basin main body is alignd, realize the automatic locking of leg support plate.
As the restriction to aforesaid way, described elastic position rebounding device is torsion spring.
As to improvement of the present utility model, between present basin main body and leg support plate, be provided with the slip of leg support plate is carried out to spacing slip stop gear.Utilize slip stop gear can realize spacing when leg support plate is relatively slided before and after seat basin main body, avoid leg support plate to come off from seat basin main body.
As the restriction to aforesaid way, described slip stop gear comprises the sliding tray that is arranged on lock groove both sides on leg support plate, and the slip limiting stopper in the described sliding tray of insertion that present basin main body is set has one end of lock groove, slidably coordinates.
As to restriction of the present utility model, described springing is the spring being connected between a basin main body and leg support plate.At leg support plate when relatively seat basin main body is in receiving state, springing is in elastic deformation energy accumulating state, thereby when lockout mechanism is opened, under the elastic-restoring force effect of springing, drive the seat basin main body motion relatively of leg support plate, realized the automatic elongation of evading panel.
In sum, adopt the technical solution of the utility model, many gears of having realized leg holder regulate, and can automatically extend after leg holder release, have good practicality.
