Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] see Figure 5 , the unlocking force and stroke adjustment mechanism 100 shown in the figure includes a fixed bracket 110 , and the fixed bracket 110 is installed on the upper slide rail 310 of the slide rail assembly 300 using fasteners such as a pair of bolts 200 .

[0032] see in conjunction image 3 with Figure 4 The slide rail assembly 300 includes an upper slide rail 310, a lower slide rail 320, a pair of ball cages 330, a number of balls 331, a tooth plate 351 constituting the slide rail locking mechanism, a pair of locking springs 352 and an unlocking pin 353. The sliding rail 310 and the lower rail 320 are slidably arranged together through a pair of ball cages 330 and a plurality of balls 331 , and the pair of ball cages 330 hold the balls 331 .

[0033] The locking teeth on the tooth plate 351 pass through the upper rail to...

Abstract

The invention provides an unlocking force and stroke adjusting mechanism. The mechanism is independently manufactured from a slide rail assembly, and is mounted in an upper slide rail of the slide rail assembly by adopting a fastener. The mechanism comprises a fixing support connected with the upper slide rail in the slide rail assembly, as well as an unlocking U-shaped support assembly, an unlocking reset spring, an inhaul cable support assembly, a small gear and a sector gear which are installed in the fixing support, the inhaul cable support assembly drives the sector gear to rotate throughthe small gear so as to drive the unlocking U-shaped support assembly to rotate, and the rotating unlocking U-shaped support assembly drives an unlocking arm on the unlocking U-shaped support assembly to act on an unlocking pin of a slide rail locking mechanism to unlock the slide rail locking mechanism. According to the mechanism, by means of the modular design, manufacturing, installation and replacement are convenient, an existing slide rail manufacturing process is not affected, meanwhile, an unlocking force and unlocking stroke adjusting range is large, and the mechanism is suitable formanual adjustment and electric adjustment to unlock a slide rail and is also suitable for motors with the same power to drive different types of slide rail assemblies to be unlocked.

Description

technical field [0001] The invention relates to the technical field of vehicle seats, in particular to an unlocking force and stroke adjustment mechanism. Background technique [0002] Currently, seat comfort adjustments are figure 1 with figure 2 in the way. figure 1 The seat comfort adjustment method shown in is to use a plastic handle to drive the cable 1 to pull the unlocking handle 3 on the seat frame 2 to unlock the slide rail locking mechanism 5 in the slide rail assembly 4. The adjustment range of its unlocking force and unlocking stroke is small, and relevant parts need to be installed on the seat frame, which is not conducive to the modularization of parts. figure 2 The seat comfort adjustment method shown in is to use the plastic handle to drive the unlocking handle 7 on the slide rail assembly 6 to unlock the slide rail locking mechanism 8 in the slide rail assembly 6. The adjustment range of the unlocking force and the unlocking stroke is small, and additi...
