Abstract
The utility model relates to a vehicle seat technical field, concretely relates to vehicle seat's back angle modulation mechanism. Its security, stability height. The utility model discloses a technical scheme include the back fixed plate, one side of back fixed plate lean against the tooth dental lamina through bolted connection, still include ratch mount, ratch, pull out the fork and ally oneself with cover and reduction torsion spring, the ratch mount on wear to be equipped with the axle, the epaxial axle sleeve that is provided with the ratch on, the ratch on the tooth with lean against the gear mesh on the tooth dental lamina, be provided with the reduction torsion spring respectively and the shift fork allies oneself with the cover both sides of ratch, reduction torsion spring one end card on the ratch mount, in other end card advanced the aperture of ratch, it is spacing with the outer surface contact of ratch that the shift fork allies oneself with the boss of sheatheeing in.
Description
One, technical field:
The utility model relates to vehicle seating art field, is specifically related to a kind of backrest adjusting angle mechanism of seat.
Two, background technology:
At present, at emergency situation by there is easily de-tooth, the insecure risk of locking in the backrest adjusting angle mechanism of automotive seat, backrest locking is unstable, and the insufficient strength of backrest adjusting angle mechanism, easily occurs that backrest cannot locking and de-tooth phenomenon when impacting energetically.
Three, utility model content:
The utility model, in order to solve the weak point in above-mentioned background technology, provides a kind of backrest adjusting angle mechanism of seat, and its safety, stability are high.
For achieving the above object, the technical solution adopted in the utility model is: a kind of backrest adjusting angle mechanism of seat, comprise backrest adapter plate, the side of described backrest adapter plate has been bolted and has leaned against teeth plate, it is characterized in that: also comprise ratch fixed mount, ratch, fork union and reduction torsion spring, described ratch fixed mount is equipped with axle, axle is provided with axle sleeve, axle sleeve is provided with ratch, tooth on described ratch is meshed with the tooth leaned against on teeth plate, the both sides of described ratch are respectively arranged with reduction torsion spring and shift fork union, described reduction torsion spring one end is stuck on ratch fixed mount, the other end sticks in the aperture of ratch, boss in shift fork union and ratch exterior surface spacing.
Described ratch fixed mount there are four boss, four holes that four boss are corresponding with backrest adapter plate are linked closely fixing, and the ratch attachment face of ratch fixed mount and boss face are welded as entirety, and ratch fixed mount is connected with backrest adapter plate bolt by upper and lower two holes.
The diameter of four boss of described ratch fixed mount is φ 3 ~ φ 8mm, and its boss height is 1 ~ 5mm.
Compared with prior art, the advantage that the utility model has and effect as follows: the utility model links closely fixing by four boss of ratch fixed mount and backrest adapter plate, and the ratch attachment face of ratch fixed mount and boss face are welded as entirety, the axial clearance of ratch and backrest teeth plate can be reduced, share load, strengthen the stability of backrest, keep the safety in driving conditions with steady, driver is taken feel at ease, comfortable, meanwhile, promote the reliability of seat entirety.
Four, accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of ratch fixed mount;
Fig. 4 is the structural representation of ratch fixed mount, shift fork union, reduction torsion spring and ratch.
Reference numeral: 1-backrest teeth plate, 2-ratch fixed mount, 3-ratch, 4-shift fork union, 5-reduction torsion spring, 6-backrest adapter plate.
Five, detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
See Fig. 1 and Fig. 2: a kind of backrest adjusting angle mechanism of seat, comprise backrest adapter plate 6, ratch fixed mount 2, ratch 3, fork union 4 and reduction torsion spring 5, the side of described backrest adapter plate 6 has been bolted and has leaned against teeth plate 1, and can rotate around attachment point, regulate the angle of backrest, ratch fixed mount 2, reduction torsion spring 5, shift fork union 4, ratch 3 are arranged within ratch fixed mount 2 also fixing by axle sleeve by tie bolt, ratch 3 is driven to rotate around axle sleeve by stirring shift fork union 4, described ratch fixed mount 2 there are four boss, four holes that four boss are corresponding with backrest adapter plate are linked closely fixing, ratch fixed mount 2 is connected with bolt with backrest adapter plate 6 by upper and lower two holes, and ratch 3 attachment face of ratch fixed mount 2 is welded as entirety with band face, boss place, the diameter of four boss of described ratch fixed mount 2 is φ 3 ~ φ 8mm, its boss height is 1 ~ 5mm, and the ratch attachment face of ratch fixed mount and band face, boss place weld together, (in order to increase the stability of backrest locking, promote the bulk strength of seat simultaneously) described in ratch fixed mount 2 on be equipped with axle, axle is provided with axle sleeve, axle sleeve is provided with ratch 3, tooth on described ratch 3 is meshed with the tooth leaned against on teeth plate 1, the both sides of described ratch 3 are respectively arranged with reduction torsion spring 5 and shift fork union 4, described reduction torsion spring 5 one end is stuck on ratch fixed mount 2, the other end sticks in the aperture of ratch 3, the convex platform of shift fork union 4 contacts with ratch 3 profile (outside face) and coordinates synchronous axial system.Rotate adjustment and unblock that shift fork union 2 just can realize backrest.
The structure of described shift fork union is one ring-like, annular is provided with handle, annular is provided with boss.
Principle of work of the present utility model is: when needs adjusting angle of backrest, shift fork union 4 is regulated to drive ratch 3 to rotate, drive reduction torsion spring 5 torsion to become large simultaneously, the flank of tooth of ratch 3 and backrest teeth plate 1 are departed from, realize backrest and unlock, chaufeur applies a power to backrest, by the position that backrest adjustment is needing, unclamp shift fork union 4, ratch 3 is by reduction torsion spring 5 homing, engage with backrest teeth plate 1, complete backrest locking.
