Vehicle Seat Leg Support with Track-Mounted Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle occupant supports often lack sufficient leg space and storage for passengers in rear seats, compromising comfort and accessibility.
Innovation Solution
A passenger-comfort module with a removable lumbar support and a leg support system, featuring a first leg support coupled to the rear occupant support and a second leg support mounted on tracks, providing adjustable and reclining functionality to enhance comfort and privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional front-row occupant support is installed, then the vehicle maintains standard seating configuration, but the rear seat passenger lacks sufficient leg space and storage accessibility
Solution Approach 1:
The front-row occupant support is completely removed from the vehicle, extracting the obstacle that was preventing leg extension. This creates an unobstructed passenger compartment allowing rear seat passengers to fully extend their legs while maintaining a simplified seating configuration with only the rear occupant support remaining.
Solution Approach 2:
The leg support system extends the seating functionality into the longitudinal dimension of the vehicle by providing an extendable leg support that projects forward from the rear occupant support, creating additional support in the previously occupied space without requiring a second seat.
2Ease of operation
If the front-row occupant support is removed to create leg space, then rear seat comfort improves, but the vehicle loses a seating position
Solution Approach 1:
The leg support system serves multiple functions: it provides leg extension support for comfort, creates a storage compartment beneath it, and maintains the structural integrity of the passenger compartment. This multi-functionality compensates for the loss of a front seat while improving rear seat comfort.
Solution Approach 2:
The leg support is designed with adjustable and movable characteristics, allowing it to adapt to different passenger sizes and preferences. This dynamic adjustability enhances comfort for various occupants while maintaining the simplified single-seat configuration.
3Ease of operation
If a leg support system is added to the rear occupant support, then leg space and comfort improve, but the device complexity increases
Solution Approach 1:
The leg support system is divided into separate modular components including the leg support structure, storage compartment, and mounting mechanisms. This segmentation allows for easier installation, maintenance, and adjustment while reducing overall system complexity through standardized modules.
