Monolithic Bracket for Vehicle Seat Tilt Mechanism

The patent merges multiple components (bracket, housing, bearing surfaces) into a monolithic bracket structure that integrates the functions of support, rotation, and bearing. This single-piece construction eliminates weld joints while maintaining all necessary mechanical functions, thereby improving both crash-worthiness through enhanced structural integrity and ease of assembly by reducing the number of parts to be assembled and welded.

The patent incorporates curved bearing surfaces with radii of curvature that enable smooth rotational movement between the bracket and housing. These curved surfaces distribute contact forces over larger areas and reduce sliding friction, thereby minimizing energy loss while maintaining a relatively simple structural design. The curved geometry allows the mechanism to achieve low-friction operation without requiring complex multi-component assemblies.

The curved bearing surfaces are designed with specific radii of curvature that balance the need for low friction with manufacturability. By optimizing the curvature radius, the patent achieves smooth rotational movement and reduced contact stress while maintaining tolerances that are feasible for standard manufacturing processes. The curved geometry naturally distributes loads, reducing the severity of precision requirements compared to flat or highly complex surfaces.

The monolithic bracket combines multiple functional elements (mounting features, bearing surfaces, rotation joints) into a single integrated component. This merging approach improves crash-worthiness by eliminating weak weld joints and creating a continuous load path, while actually reducing device complexity by decreasing the total number of parts, fasteners, and assembly steps required.
