Description
Technical field
The present invention relates to automotive seating art field, more particularly to a kind of Inertial lock mechanism for seat.
Background technology
In the vehicle of double leval jib function seat, when being hit before generation, front rod is rotated freely around pivot point, and power can not lead to
Cross front rod and be delivered to slide rail, upper connecting rod rear end and the sliding rail rear end of effectively all concentrating on, Traditional solutions are usually to strengthen
Upper connecting rod and sliding rail rear end, the power for allowing upper connecting rod to be hit before withstanding, but this method skeleton is heavier, high cost；Therefore demand
A kind of new inertial lock, in collision process, pins front rod, allows part power to be delivered on slide rail by front rod.
Referring to Fig. 1 to Fig. 3, the Inertial lock mechanism be given in figure, its operation principle is as described below：When vehicle hits before occurring,
Inertia locking plate 1 rotates forward in the presence of inertia force around rotating shaft 2, while backrest 3 rotates forward around the center of recliner 4,
When rotating to certain angle, the catch point 5 on inertia locking plate 1 and backrest 3 is stuck, and backrest 4 can not continue to rotate forward.Its advantage is
Backrest 4 can contemplate and use unilateral recliner or the less recliner of moment of torsion；Have the disadvantage the friction of inertia locking plate 1 and rotating shaft 2
Power is not easily controlled, if frictional force is too small, abnormal sound may occur when normally using, preceding to rise when hitting if frictional force is too big
Effect.Other rotating shaft 2 needs increase reinforced support 6 to be strengthened, and increased cost.Also it is exactly that the inertia locking plate is not used to
The pinning of front rod.
The content of the invention

Edge is curved；The inertia locking plate reduction torsion spring on the inertia locking plate bearing pin, the one of the inertia locking plate reduction torsion spring
End is acted on the inertia locking plate, and the other end is acted on the sliding rail rack；When being hit before vehicle generation, the inertial lock
Upset, to being contacted with the catch point of the front rod, by the front rod locking, makes the front rod to piece forward under effect of inertia
Do not overturn further along, and guarantee section impact is delivered to sliding rail rack and is delivered to slide rail by sliding rail rack by front rod
On.
In being preferable to carry out at one of the invention, an arc guide groove is offered on the sliding rail rack, described used
A guide finger is provided with property locking plate, one end of the guide finger is embedded into the arc guide groove；At the inertia locking plate
When normal position, the guide finger is in the rear limit point of the arc guide groove, and the inertia locking plate is in lock position
When, before the guide finger is in the limit point of the arc guide groove.
In being preferable to carry out at one of the invention, the inertia locking plate is sector structure.
In being preferable to carry out at one of the invention, the lower edge of the inertia locking plate is provided with an arc locking and strengthens
Plate, is provided with an arc and strengthens baffle plate in the catch point position of the front rod, described when the inertia locking plate is in lock position
Arc locking reinforcing plate is strengthened baffle plate and is contacted with the arc.
As a result of technical scheme as above, when being hit before vehicle generation, Inertial lock mechanism can quick locking for the present invention
Front rod, it is ensured that part power can be delivered on sliding rail rack by front rod and is delivered on slide rail by sliding rail rack, can
To weaken upper connecting rod and sliding rail rear end support.
