Description

Structure for preventing rear-row large handrail from shaking

Technical Field

The utility model relates to a car seat spare part technical field, concretely relates to a structure for preventing big handrail of back row from rocking.

Background

The rear-row large handrail in the current market usually adopts a low-position locking structure, and for the low-position locking structure, the distance from the end part of the handrail to the handrail rotating shaft is dozens of times, even twenty times, the distance from the handrail limiting shaft to the handrail rotating shaft. Because manufacturing process tolerance, assembly tolerance, etc. can't avoid, the spacing pin cooperates with the shaft hole of handrail support even only has the clearance about 0.5mm, enlargies behind tens twenty times, can lead to big handrail of back row to have more than 5mm, even reach tens of millimeters clearance of activity under the locking state. That is, when the vehicle is accelerated and decelerated or passes through a road surface which is not particularly flat, the end portions of the armrests will shake back and forth, which generates abnormal sound, thereby not only affecting the riding comfort of the automobile seat and making the passengers feel that the seat does not have a high-grade feeling, but also failing to meet the requirement of some high-demand automobile manufacturers on Freelay (when the end portions of the armrests are subjected to small force when the armrests are in a closed and locked state, the armrests will shake back and forth).

Therefore, some automobile seat manufacturers add a soft buffer element on the decorative plate of the back row large armrest, which can play a certain buffer effect to prevent the back row large armrest from being hard-touched with the decorative plate. However, the interference amount of the soft buffer can only be small, and if the interference amount is large, the large handrail in the back row may be resisted and cannot be locked. And because spare part manufacturing tolerance and assembly tolerance can not be avoided, and soft bolster self thickness can not adjust, lead to soft bolster suitability not enough, can not perfectly match all big handrails of back row, discover in actual production, still have a large amount of big handrails of back row can take place the problem of rocking from beginning to end when closed locking state. It is urgent to solve the above problems.
