Vehicle Seat Fitting Radial Play Minimization

The patent applies preliminary action by pre-configuring the bearing bush and third fitting part with specifically positioned elevations that automatically minimize play when assembled in the locked state. The elevations are designed to rest against each other in a way that eliminates radial play without requiring post-assembly adjustment or turning back the bearing bush, thus achieving both play minimization and jamming avoidance in advance.

The patent changes the geometric parameters of the bearing bush and third fitting part by providing multiple elevations on specific surfaces. These elevations are positioned to interact in a way that transforms the bearing interface from having significant play to having minimized play in the radial direction when locked, while maintaining the necessary clearance for free pivoting operation.

The patent pre-configures the elevations on the bearing ring and third fitting part to automatically minimize radial play when assembled in the locked state. This preliminary configuration ensures that the play is minimized for quality perception while the design inherently prevents complete elimination that would cause jamming, thus resolving the contradiction between quality perception and reliability.

The patent applies local quality by providing elevations at specific locations on the bearing ring and third fitting part. These elevations are strategically positioned to minimize play in the radial direction where quality perception is critical, while maintaining appropriate clearance in other areas to prevent jamming during operation. The elevations create localized contact points that improve perceived quality without compromising overall system reliability.
