Detachable Vehicle Seat Base With Shared Backrest Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seating solutions in stationary vehicles lack flexibility and safety, as they do not allow for the conversion of seating arrangements to accommodate different user needs or configurations, particularly when the vehicle is stationary, and there is a need for innovative designs that enhance occupant comfort and safety.
Innovation Solution
The design incorporates a seating assembly with a primary seat and an auxiliary seat that can be selectively coupled and decoupled via an engaging member, allowing the auxiliary seat to pivot between stowed and deployed positions, with a common backrest that supports both seats, enabling versatile seating configurations and enhanced occupant comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed seating arrangement is provided in the vehicle, then the structural simplicity is maintained, but the adaptability to different user needs is reduced
Solution Approach 1:
The seating assembly is divided into separable components: a primary seat base and a secondary seat base that can be independently positioned. The secondary seat base can be detached from the primary seat base, allowing the seating configuration to be re arranged or removed entirely, thus providing adaptability without requiring a completely complex system
Solution Approach 2:
The seating assembly incorporates movable elements including the secondary seat base that can pivot between stowed and deployed positions, and support legs that can extend and retract. These dynamic components allow the seating arrangement to adapt to different configurations while maintaining a relatively simple overall structure when in a fixed state
2Adaptability or versatility
If an auxiliary seat is added to the vehicle, then the seating versatility is improved, but the space availability is reduced
Solution Approach 1:
The secondary seat base is designed to nest against the backrest of the primary seat when in the stowed position. This nesting arrangement allows the auxiliary seating capability to be stored within the existing seating structure, minimizing the space occupied when the auxiliary seat is not in use while still providing additional seating when needed
3Ease of operation
If the seat base is made detachable, then the ease of operation is improved, but the reliability is reduced
Solution Approach 1:
The connection between the primary and secondary seat bases transitions from a static fixed connection to a dynamic conditional connection. The support legs provide a mechanical linkage that can be engaged or disengaged, allowing the system to switch between a reliable connected state for ease of operation and a detachable state for flexibility
Solution Approach 2:
The support legs act as an intermediary mechanism between the primary and secondary seat bases. This intermediary component provides a controlled connection that can be easily engaged and disengaged while maintaining stability when connected, resolving the conflict between ease of operation and reliability

AI summary
A vehicle includes a first seat. A seat base is selectively coupled to the first seat via an engaging member extending from a proximal end of the seat base. The seat base has an attached configuration and a detached configuration. The seat base couples with the first seat and forms a second seat facing away from the first seat in the attached configuration. The seat base is decoupled from the first seat in the detached configuration. A backrest is common to the first and second seats in the attached configuration. A frame structure operably couples the first seat with the vehicle. The frame structure includes a receiving member interfacing with the seat base. The engaging member engages the receiving member to couple the seat base with the backrest.
