Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile seat, specifically relates to a massage head hidden control mechanism. BACKGROUND

[0002] In order to improve the fatigue of the passenger and improve the driving comfort, the massager is usually configured on the vehicle seat.

[0003] Regarding the massage function of the seat, the mainstream technology is to install the air bag in the backrest of the automobile seat, and the massage purpose is achieved by regular inflation and deflation of the air bag. In the prior art, the air bag is integrated in the waist and back of the passenger, and the fatigue of the passenger's shoulder is ignored. Although a few manufacturers set massage air bags at the shoulder position of the seat, the overall pressing force of the air bag massage is not enough, and the overall comfort of the seat needs to be improved.

[0004] In view of the above problems, the applicant intends to put forward a massager which simulates kneading to massage the passenger's shoulder. This method can increase the overall massage intensity and comfort, but since the massage head is a hard component, when the massager is turned off, the massage head protrudes from the surface of the seat shoulder. When the passenger's shoulder leans on the automobile seat, the passenger can obviously feel the sense of suffocation brought by the massage head, and the comfort needs to be optimized and upgraded. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model provides a massage head hidden control mechanism, which can make the massage head inwardly retract after the massager is turned off to avoid the sense of suffocation.
