Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in fig. 1 to 3, a slide rail unlocking mechanism for an automobile seat comprises an upper slide rail 2 and a lower slide rail 1 which are in sliding fit, wherein the section of the upper slide rail 2 is n-shaped, the upper slide rail comprises a horizontal supporting part 2a and a longitudinal supporting part 2b extending downwards from two ends of the horizontal supporting part 2a, a bracket 3 is fixedly installed at the lower side of the horizontal supporting part 2a, the bracket 3 comprises a horizontal mounting plate 3a and side fixing parts 3b extending upwards from two ends of the horizontal mounting plate 3a, the side fixing parts 3b are riveted at the lower side of the horizontal supporting part 2a through rivets 9, a mounting cavity is formed between the horizontal mounting plate 3a and the horizontal supporting part 2a, two groups of guide posts 4 arranged along the vertical direction are slidably sleeved on the horizontal mounting plate 3a, the guide posts 4 penetrate through the horizontal mounting plate 3a, the upper ends of the two groups of guide posts 4 are commonly connected with unlocking, all the cover is equipped with spring 7 on the guide post 4, and spring 7 butt is being separated between locking plate 5 and horizontal mounting plate 3a, and 6 width direction's of locking plate both sides distribute has the lock tooth 6a of rectangle block structure, and the inboard of lower slide rail 1 upper end all has downwardly extending's turn-ups 1b, and turn-ups 1 b's lower extreme distributes along 1 length direction of lower slide rail has locked groove 1a, and locked groove 1a is the open dovetail groove of lower extreme.
