Vehicle Seat Gap Blocking Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seats allow foreign matters to enter through gaps between the seat pad and adjacent members, compromising the integrity of the seat's internal environment.
Innovation Solution
A vehicle seat design featuring an elastic support body with a protruding portion that blocks the gap between the seat pad and adjacent members, preventing foreign matters from entering the inner area by utilizing a foamed urethane cushion pad and a bead foam molded body with a protruding portion that extends between the pedestal frame and resin cover, effectively sealing the gap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a gap is provided between the seat pad and adjacent member, then ease of assembly and manufacturing flexibility are improved, but foreign matters can enter the inner area of the seat
Solution Approach 1:
The protruding portion is formed in advance within the elastic support body during manufacturing, creating a preventive barrier before the seat is assembled and used. This preliminary structural feature ensures that foreign matters cannot enter through the gap without requiring additional assembly steps or complex sealing mechanisms.
Solution Approach 2:
The protruding portion acts as an intermediary element between the elastic support body and the frame material, physically blocking the gap and preventing foreign matter transmission while maintaining the necessary space and flexibility for assembly and movement.
2Adaptability or versatility
If the seat pad is made elastic and resilient, then comfort and adaptability are improved, but the gap can open under load allowing foreign matters to enter
Solution Approach 1:
The protruding portion creates a localized barrier within the elastic support body that maintains its blocking function specifically at the gap region, while the rest of the seat pad retains its elastic and resilient properties for comfort and adaptability under various load conditions.
Solution Approach 2:
The protruding portion is pre-formed within the elastic support body to anticipate and prevent foreign matter entry that could occur under load conditions, ensuring protection is in place before any deformation or gap opening occurs during use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents foreign matters from entering the inner area of the seat, maintaining a clean and secure environment by utilizing the resilient force of the bulging portion and the structural rigidity of the protruding portion to block the gap, even under load conditions.
Implementation Method 1
an elastic support body including a seat pad... the elastic support body has a protruding portion which protrudes between the adjacent member and the frame material
Implementation Method 2
foreign matters can enter between the seat cushion and the vehicle body from the outside against a resilient force of the pad material

AI summary
A vehicle seat including: an elastic support body including a seat pad; and an adjacent member adjacent to the seat pad, wherein a gap is provided between the elastic support body and the adjacent member and extends toward an inner area of the seat in which a frame material is provided, and wherein the elastic support body has a protruding portion which protrudes between the adjacent member and the frame material and is configured to block the gap.
