Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a footless slide rail for automobile seats. Background Art

[0002] The slide rail is one of the components of the car seat and is the main actuator for adjusting the front and rear of the car seat. It is also closely related to our driving safety. By adjusting the position of the seat through the slide rail, it is convenient for passengers to operate or get on and off the car, and can provide passengers with a more comfortable space.

[0003] When the electric slide is in use, the controller is used to adjust the front and rear position of the car seat. However, the slide is fixedly connected to the floor of the vehicle through mounting feet. The mounting feet inside the slide need to avoid slide parts, which is difficult to process and has high cost. At the same time, the motor and the connecting shaft will produce large shaking when running. For this reason, we propose a slide without mounting feet for car seats. Utility Model Content
