[0002] The height of a car seat cushion is adjusted by a gear in the height adjuster engaging with a toothed sector of the cushion. Traditionally, the toothed sector is a single, molded piece, formed by stamping. To ensure precise meshing between the toothed sector and the gear, this one-piece toothed sector is manufactured using a precision stamping process. Furthermore, to guarantee its strength, the entire one-piece toothed sector requires sufficient material thickness. This type of one-piece toothed sector exhibits poor energy absorption in collisions, making it prone to breakage. Breakage can easily cause secondary injuries to passengers. Moreover, the traditional design of the toothed sector and rack requires precision stamping, resulting in higher costs.

[0003] Therefore, it is necessary to design an energy-absorbing toothed fan for automotive seats to improve the above problems. Utility Model Content

[0025] Reference Figures 1 to 3 , Figure 1 This is a perspective view of the present invention. Figure 2 This is the front view of this utility model. Figure 3 This is an exploded view of the present invention. The present invention provides an energy-absorbing toothed fan for automotive seats, comprising a toothed fan body 1 and a rack 2. The toothed fan body 1 is connected to related seat components, and the rack 2 is connected to the toothed fan body 1. The rack 2 is arc-shaped and has teeth 21. Both the toothed fan body 1 and the rack 2 have fixing holes 3. There are multiple fixing holes 3. The spacing between two adjacent fixing holes 3 on the toothed fan body 1 or the rack 2 is the same. The separate toothed fan body 1 and the rack 2 are fixedly connected by connectors through the fixing holes 3 to form a fixed integrated structure. Compared with the traditional integrated toothed fan, this structure has better energy absorption performance in collision conditions.

[0026] The gear sector body 1 is provided with a limiting groove 11, a first connecting hole 12, and a second connecting hole 13.
