Integrated Seat Grip for Multi-Occupant Vehicle Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat structures for rough-terrain vehicles do not provide an efficient and cost-effective way for passengers to grip a support near their body, leading to increased costs due to additional parts required for separate grip members.
Innovation Solution
A seat structure with a single seat designed for multiple occupants, featuring a seat grip integrated into the lower face of the seat and a frame grip on the body frame, allowing occupants to grip with one hand each, reducing the need for additional parts and enhancing body support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate grip member is provided on the seat near the passenger's body, then the passenger can grip it for body support, but the number of parts increases causing cost increase
Solution Approach 1:
The grip function is merged with the existing seat structure by forming the seat grip as an integral part of the seat's lower face. This eliminates the need for separate grip members while maintaining the body support capability, directly resolving the contradiction between ease of operation and device complexity
2Ease of operation
If a separate grip member is provided on the seat near the passenger's body, then the passenger can grip it for body support, but the manufacturing cost increases
Solution Approach 1:
The seat grip is combined with the seat structure as a single integrated component. This merging reduces the total number of parts that need to be manufactured and assembled, thereby lowering manufacturing costs while still providing the necessary body support function
3Adaptability or versatility
If the seat is designed for multiple occupants side by side, then seating capacity is improved, but providing individual grips for each occupant increases part complexity
Solution Approach 1:
The seat structure is designed with a universal lower face that serves multiple functions: it provides seating support for multiple occupants and simultaneously offers grip surfaces for body support. This multi-functionality allows the same structure to serve both seating and gripping purposes without adding complexity

AI summary
A vehicle having a single seat for a plurality of occupants sitting side by side in a lateral direction of the vehicle. The seat has a front end recessed rearwardly at a center seat portion so as to form a substantially U-shaped recess as viewed in a plan view. The recess is composed of a bottom portion and a pair of left and right side portions extending obliquely in a forward direction from the left and right ends of the bottom portion. At a left corner portion of a right seat portion where the right side portion of the recess intersects the front end of the right seat portion, there is provided a seat grip for gripping by the occupant sitting on the right seat portion. The occupant can easily grip the seat grip with his/her hand in the vicinity of his/her body, thereby obtaining good support for the body.
