Hanging Vehicle Seat With Transverse Suspension Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle-mounted seats with a chair type form are heavy and large due to the need for a hard skeleton member, and existing hammock-like car accessories used for sleeping in vehicles lack stability, causing occupants to rotate and lose posture stability during travel.
Innovation Solution
A hanging type seat design that uses front, rear, and transverse hanging tools to suspend the seat main body within a vehicle, eliminating the need for a skeleton member and incorporating a net-like first support member for flexibility, which divides the occupant's upper and lower body movements to maintain stability and absorb road vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hard skeleton member is used to form a chair type seat, then the seat can maintain its shape and support the occupant, but the weight and size of the seat increase significantly
Solution Approach 1:
The patent replaces the hard skeleton member with a flexible net member that has elastic properties. The net member is formed by weaving or knitting elastic threads, allowing it to flexibly support the occupant's body while maintaining the necessary shape through its elastic recovery, thereby significantly reducing weight compared to rigid skeletal structures
Solution Approach 2:
The seat adopts a dynamic hanging structure where the net member can dynamically adjust its shape and support characteristics based on the occupant's position and movement. The elastic net member absorbs and responds to body movements, providing adaptive support without requiring rigid structural elements
2Weight of moving object
If only front and rear hanging tools are provided, then the seat weight is reduced, but the seat tends to rotate around the front-back axis, making it hard to keep the occupant in a stable posture
Solution Approach 1:
The patent adds transverse hanging tools that extend in the lateral direction (width dimension) in addition to the front-back hanging tools. This multi-dimensional hanging configuration creates a more stable suspension system that prevents rotation around the front-back axis by providing support points across the width of the seat, thereby improving stability without significantly increasing weight
3Device complexity
If the seat main body is made as a single unit, then the structure is simple, but the occupant's upper and lower body movements cannot be adjusted separately
Solution Approach 1:
The patent divides the seat main body into multiple independent support members (first support member for upper body, second support member for lower body). Each support member can move independently relative to the others, allowing separate adjustment of upper and lower body positions and movements, thereby improving adaptability while maintaining relatively simple overall structure

AI summary
A hanging type seat mounted in a vehicle comprises a seat main body for supporting an occupant from below; one or more front hanging tools which are passed across a front part of the seat main body, extended upward in the front-back direction, and attached to a structure in the vehicle; one or more rear hanging tools which are passed across a rear part of the seat main body, extended upward in the front-back direction, and attached to a structure in the vehicle; and two or more transverse hanging tools which are passed across both sides of the seat main body, extended laterally upward, and attached to a structure in the vehicle; wherein the seat main body is hung and held by the one or more front hanging tools, the one or more rear hanging tools, and the two or more transverse hanging tools.
