Modular Bus Seat With Lumbar Support And Retractor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bus seats are uncomfortable, unsightly, and poorly spaced, failing to provide optimal comfort and safety due to regulatory constraints and lack of technological innovation.
Innovation Solution
The bus seat design incorporates a lumbar support, concave rear-facing seat frame, wire mesh frame core, and modular retractor system, along with an integrated booster seat and child restraint system, to enhance comfort and safety while maintaining compliance with safety regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional bus seat design is used, then manufacturing simplicity is maintained, but passenger comfort deteriorates due to poor knee spacing and backrest angle
Solution Approach 1:
The seat is divided into modular components including a seat pan, backrest, lumbar support, and base assembly that can be independently manufactured and assembled. This segmentation allows each component to be optimized for comfort while maintaining manufacturing simplicity through standardized production processes.
Solution Approach 2:
The lumbar support is designed as a dynamic component that can adjust to different passenger needs and seating positions. This dynamic element improves comfort by adapting to individual passengers while the overall seat structure remains simple and manufacturable.
2Ease of operation
If lumbar support and concave rear facing seat frame are added, then knee spacing and backrest angle are optimized for comfort, but device complexity increases
Solution Approach 1:
The concave rear facing seat frame applies local quality by creating a specifically shaped support surface in the rear portion of the seat. This localized geometric modification optimizes knee spacing and backrest angle without requiring complex adjustments throughout the entire seat structure.
Solution Approach 2:
The lumbar support incorporates curved surfaces that conform to the natural curvature of the human spine. This spherical/curved geometry provides ergonomic comfort and optimal backrest angle while being manufacturable through standard forming processes.
3Adaptability or versatility
If modular retractor design is implemented, then adaptability to different orientations is improved, but device complexity increases
Solution Approach 1:
The modular retractor design creates a universal component that can function in multiple orientations (vertical and horizontal) and be installed in different locations on the seat. This multi-functional approach provides adaptability while using standardized modular components that simplify rather than complicate the overall system.

AI summary
A bus seat is provided. The bus seat includes a backrest frame having a curve in part and a lumbar support coupled to the backrest frame by the curve. The bus seat also includes a horizontal seat that is pivotable from a seat position, where a seat frame is locked onto a base frame, to a stowed position. The bus seat is provided in a modular configuration to allow multiple backrests to be used for the bus seat. The backrests may include changeable seat belt configurations and child restraint system configurations. The bus seat also includes a seat belt retractor having a vertical configuration and a horizontal configuration for retracting and extending the seat belt.
