Abstract
The utility model discloses a noise-proof spring, which is applied to a car seat, and comprises a spring body which is formed by integrally bending, wherein the two ends of the spring body are respectively provided with a hook, and a protective sleeve is sleeved outside each hook and is made of hard plastic. The plastic protective sleeves are arranged on the hooks at the two ends of the spring body, accordingly, when the car seat bears force, the friction between the plastic protective sleeves and a metal frame is generated to avoid the generation of noise, and the plastic protective sleeves also play a certain protective role for the spring hooks; and the noise-proof spring not only has a simple structure and a low cost, but also has no noise when in use, and has a long service life.
Description
Technical field
The utility model relates to a kind of spring, particularly relates to a kind of noise-proofing spring that is used for the car seat.
Background technique
At present; various springs are by extensively in being used in industrial production and large-tonnage product; the vehicle seat of automobile for example; in order to increase the comfort level that people use; the capital is provided with many with spring on seat and backrest; utilize the deformation of spring to cooperate the action of human body to reach easy to use; comfortable effect; but; traditional saddle springs generally all is to be formed by the bending of steel wire one, comprises the hook at spring body and body two ends, utilizes hook that spring is arranged on the Steel Support of vehicle seat; like this when vehicle seat is stressed; can produce a bigger friction on hook and the vehicle seat support, send bigger noise through regular meeting, and the friction of hook and vehicle seat support also can cause bigger infringement to spring; time has been grown hook is fractureed, and causes spring to use.
