A massage device for the back of a car seat

Abstract

The invention provides a massage device for the seat back of an automobile seat. The massage device comprises a half-frame rack, wherein the half-frame rack comprises a standing plate; an upper fixing plate and a lower fixing plate are respectively arranged at the upper part and the lower part of the standing plate; at least one roller shaft made of polyurethane rigid foam is arranged between the upper fixing plate and the lower fixing plate, and the roller shafts are equally spaced. As the polyurethane rigid foam material is adopted, the massage device is relatively light; glass fiber layers wrap rollers to play dustproof and abrasion-proof roles; convex points 7 on the rollers can be directly used for massage; owing to the filling function of elastic cotton on the back side of the whole massage device, the whole massage device can be in full contact with the inner side of the seat back, as spandex layers are relatively rough, friction between the whole massage device and the seat back can be increased; as the spandex cannot damage the surface of the inner side of the seat back, the massage effect cannot be influenced by up-and-down sliding of the massage device.

Description

technical field [0001] The invention relates to the field of automobile production, in particular to a massage device for the seat back of an automobile seat. Background technique [0002] Existing car seats are extremely prone to fatigue during long-distance travel or long-term driving, especially the back is prone to tension, so people who work for a long time or travel for a long time are likely to cause physical damage or The driver's long-term fatigue causes occupational diseases. The existing car seat back generally only adds a massage cushion at the front of the seat back, and massage bumps are set on the massage cushion. This setting is based on human mechanics. When the human body is driving or sitting on the seat for a long time, the massage cushion The massage effect played is very poor, and the contact between the massage cushion and the seat is easy to slide, which further reduces the massage effect.
