The specific embodiment

As shown in Figure 1, 2, 3, a driver seat is arranged, by the support that is installed on the ground-surface seat frame of operator's compartment, mount pad basin (being the chassis that seat cushion is installed usefulness) usefulness, support and bindiny mechanism between them and the adjusting mechanism formation that the installation backrest is used.Said adjusting mechanism promptly is the driver seat adjusting mechanism, comprises the recliner of regulating backrest angle and the adjusting slide rail of adjustment seat basin front and back position.

Wherein regulate slide rail by interior external chute, external chute 3 is the C shape that opening makes progress, and roller between internal chute 17 and the interior external chute etc. wherein is installed, and internal chute is with synthetic " youngster " font structure in both sides.The big set square bottom and the internal chute Outboard Sections that constitute recliner are riveted into one, and also have a big set square of pair and inside part to be riveted into one, and both are riveted into one again, by constituting the firm big set square and the integral piece 2 of internal chute a bit.The inboard riveted joint of this integral piece has locking teeth board mount 18, and both sides, locking teeth board mount front and back are inwardly turned up and punched into axle bed 9, and the axle 6 of an outside bending of front end is installed in the hole, are fixed with locking tooth plate 7 on the axle, and locking tooth plate bottom has two lock teeth.The internal chute inside part has the lock perforation that inserts for these two lock teeth, has on the external chute madial wall by the equidistant row's locking perforation arranged of two lock interdental spaces, and the locking teeth board mount is in that to have locking teeth partly to have scarce.Locking teeth can by lack on the locking teeth board mount, the locking perforation inserts on the internal chute in the locking perforation on the external chute, thereby with interior external chute locking, make seat can not before and after slide.Aforementioned fixation has the locking tooth plate and its outer folding part of hinge branch that is articulated in the locking teeth board mount is inserted in the rear end of chute locking spanner driver plate 4, this driver plate is articulated on the integral piece with chute locking latch release shaft 16, and driver plate respectively has a little axle that inwardly stretches out in the drive-connecting shaft both sides.Chute locking spanner 1 is arranged, be to be the parts that the pipe link two ends of both sides chute locking spanner respectively are fixedly connected with chute locking spanner interlock plate 15 in the middle of one, the hole that is nested with little axle respectively and on the driver plate on the two ends interlock plate and drive-connecting shaft is installed in both sides and regulates between the slide rail.The driver plate rear end is connected with integral piece with locking teeth sheet reset spring 8 with driver plate retracing spring 5 respectively with the locking tooth plate outside.Be meant inside and outside the described front and back that the people is sitting in the direction on the seat, both sides are in the middle of export-oriented being to the left and right.

Recliner 11 main shaft inboards are with adapter shaft 14, driver plate 13 behind the captive joint of adapter shaft two ends, and the driver plate swinging end interlocks with interlock plate 12 swinging ends, and the rotational axis hole of interlock plate is enclosed within on the main shaft.There is a minor axis in the interlock plate swinging end outside, and the arcuate socket that this minor axis sees through on the big or small set square cooperates with hole on the recliner spanner 10, and recliner spanner rotational axis hole also is enclosed within on the main shaft.Pair mechanism of recliner lockout mechanism release is arranged on the recliner spanner.The recliner spanner is installed in the protective case of the recliner outside, and is divided into initiatively spanner and by wrench, and initiatively spanner is the complete spanner that handle is arranged and can be the spanner of incomplete no handle by wrench.

During operation, mention and regulate the slide rail spanner, the interlock plate of both sides is pulled driver plate according to drive-connecting shaft and through minor axis simultaneously, driver plate drive again locking tooth plate drive-connecting shaft make locking teeth deviate from locking teeth on the external chute, this moment can before and after the pulling seat.Move to and loosen spanner behind the required position then under the effect of two retracing springs, locking teeth inserts two-layer locking perforation the seat fore-and-aft direction is locked.When pulling recliner active spanner, this pulls angle driver plate after minor axis on the interlock plate makes the interlock plate swing synchronously and stir, the swing of back driver plate is swung through being transferred on the another side recliner with the adapter shaft of its captive joint and making by wrench by opposite approach, thereby reaches the purpose of both sides synchronizing unlocking.Pull its angle of back of seat scalable after the release, loosen spanner during to required angle, the both sides retracing spring makes the lockout mechanism locking.
