Vehicle Seat Internal Support Member Clip Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in assembling clips to inclined portions of internal support members in vehicle seats due to the need for mounting on inclined surfaces, leading to poor assembly efficiency and potential instability of the internal support member relative to the seat frame.
Innovation Solution
Incorporating tubular portions on the inclined portions with mounting holes and shoulder surfaces to facilitate efficient clip mounting and reinforcing structures like grid-like and longitudinal end reinforcing portions to enhance stiffness and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mounting portions are provided on the back side of the inclined portions, then the assembly work for mounting clips is facilitated, but the mounting efficiency remains poor when clips are mounted on inclined surfaces
Solution Approach 1:
The patent introduces tubular portions that extend in a direction substantially orthogonal to the main body of the internal support member, creating a third dimension for mounting. The mounting holes are formed in the tubular portions, allowing clips to be mounted from the side rather than from the inclined surface, thereby resolving the contradiction between ease of operation and assembly efficiency
Solution Approach 2:
The tubular portions act as intermediary structures between the inclined portions and the clips. Instead of directly mounting clips on the inclined surfaces or on the back side, the tubular portions provide an intermediate mounting interface that facilitates efficient assembly while maintaining ease of operation
2Adaptability or versatility
If mounting portions are provided on the inclined portions, then clips can be secured to the internal support member, but the assembly work becomes inefficient due to the inclined surface geometry
Solution Approach 1:
The tubular portions extend in a direction substantially orthogonal to the main body, providing a side mounting surface that is accessible from the lateral direction. This dimensional change allows clips to be mounted efficiently without having to work on the inclined surface, while still maintaining the adaptability to secure various components
3Ease of operation
If mounting portions are provided on the back side of the inclined portions, then assembly work is facilitated, but the stiffness of the internal support member may be reduced
Solution Approach 1:
The tubular portions are provided only at specific locations where mounting is required, rather than throughout the entire structure. This localized approach allows for efficient assembly at the tubular portions while maintaining the overall stiffness and strength of the main body and inclined portions
Solution Approach 2:
The tubular portions can be formed by integrating different materials or structures, combining the mounting functionality with structural support. The tubular portions may be made of the same material as the main body or integrated during molding, creating a composite structure that maintains stiffness while enabling easy mounting

AI summary
A vehicle seat includes: a frame provided in at least one of a seat cushion and a seat back; an internal support member for supporting an occupant, the internal support member including a main body in plate or sheet form positioned within the frame and extending substantially in parallel with the frame, and a pair of inclined portions extending laterally outward from at least a part of either lateral side of the main body with a slant away from the frame; a pad placed on a front side of the frame and the internal support member; a skin member covering the pad; and a clip securing another member to one of the inclined portions. The one inclined portion is formed with a tubular portion projecting from a back side thereof orthogonally to the main body, the tubular portion internally defining a mounting hole receiving the clip therein.
