Vehicle Seat Ottoman Storage Mechanism for Space Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat designs with ottoman mechanisms struggle to effectively extend luggage compartment and walk-through spaces, as the ottoman often restricts seat movement when trying to enhance these areas, leading to insufficient space due to contact with the seat back or other obstacles.
Innovation Solution
A vehicle seat with a foldable ottoman that includes a storage locking mechanism allowing the ottoman to move in a direction opposite to its extraction, enabling it to be stored and thus allowing the seat cushion to slide further forward, thereby increasing luggage compartment and walk-through space by separating the ottoman from the seat back during storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ottoman is provided on a seat to enhance comfort and space utilization, then the seat functionality is improved, but the seat movement and space extension capability is restricted when the ottoman contacts the seat back
Solution Approach 1:
The ottoman is designed with movable and foldable characteristics, allowing it to dynamically change its position and configuration. The ottoman can be folded toward the rear of the seat cushion or moved to a storage position, enabling the seat to slide forward without the ottoman contacting the front seat back, thus resolving the contradiction between ottoman functionality and seat movement capability
Solution Approach 2:
The ottoman is separated from the fixed seat structure and made as an independent movable component. This segmentation allows the ottoman to be independently positioned, folded, or stored without affecting the overall seat movement, enabling the seat cushion to slide forward while the ottoman is stored in a rear position
2Ease of operation
If the seat is designed with an ottoman mechanism to provide additional comfort, then the seat comfort is improved, but the luggage compartment space and walk-through space extension is insufficient
Solution Approach 1:
The ottoman is designed to be movable and foldable, allowing it to be positioned in a storage location at the rear of the seat cushion when not in use. This dynamic reconfiguration enables the seat to be slid forward to its limit position, maximizing the luggage compartment space and walk-through space while maintaining ottoman functionality when needed
3Stability of the object's composition
If the ottoman is fixed in position to maintain stability, then the ottoman structural integrity is improved, but the seat cannot slide forward sufficiently to extend space
Solution Approach 1:
The ottoman is designed with movable characteristics, allowing it to be positioned in a storage location at the rear of the seat cushion during seat sliding operations. This enables the seat to slide forward to its limit position without the ottoman contacting the front seat back, maximizing the slide distance while maintaining ottoman stability when positioned and locked in use

AI summary
A vehicle seat includes: a base mounted to a floor of a vehicle; a seat cushion that is placed on the base and allowed to be tipped up with a rotating shaft as a fulcrum; an ottoman that is provided on a front side of the seat cushion and extractable between a normal position and an extracted position; a seat back that is provided in a rear end of the seat cushion; and a storage locking mechanism that is capable of relatively moving the ottoman with respect to the seat cushion in a storing direction which is a direction opposite to an extracting direction, wherein the storage locking mechanism is operated such that the seat back becomes in a forward-tiltable state and/or the seat cushion becomes in a tippable state, and locking of the locking mechanism is released so that the ottoman becomes movable in the storing direction.
