Vehicular Seat Lock Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular seats with adjustable features face difficulties in maintaining a lock release state, making it hard to set the seat to desired positions due to momentary lock state changes and requiring additional operations to release interlocks, complicating the configuration and usability.
Innovation Solution
A vehicular seat design incorporating a cooperatively moving apparatus with a main and sub cooperatively moving member and a hold mechanism that maintains the lock apparatus in a lock release state for a predetermined time, allowing the second member to be adjusted to various set states before locking, facilitating easy adjustment to desired positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lock apparatus is released directly by the cooperatively moving apparatus, then the lock release state is achieved, but the lock state changes momentously making it difficult to set the member to a desired set state
Solution Approach 1:
The hold mechanism performs preliminary action by maintaining the lock apparatus in the lock release state before the adjustment operation is completed. This preliminary holding action ensures the member remains adjustable during the entire adjustment process, preventing momentary lock state changes that would interfere with setting the member to the desired position.
Solution Approach 2:
The hold mechanism acts as an intermediary between the cooperatively moving apparatus and the lock apparatus. It receives the release signal from the cooperatively moving apparatus and maintains the released state, mediating the transition to ensure stable lock release condition during the adjustment operation without direct momentary locking.
2Stability of the object's composition
If an interlock is used to maintain the lock release state, then the lock release state is maintained, but an additional operation for releasing the interlock is needed
Solution Approach 1:
The hold mechanism merges the functions of maintaining lock release state with the existing cooperatively moving apparatus operation. By integrating the holding function into the same operational flow that releases the lock, the system maintains stable lock release state without requiring a separate interlock release operation, thus reducing overall operational complexity.
Solution Approach 2:
The hold mechanism provides multi-functionality by simultaneously serving as both the release mechanism and the maintaining mechanism for the lock release state. This universal component performs multiple functions (releasing and holding) within a single operational sequence, eliminating the need for separate interlock release operations.
3Reliability
If the lock apparatus switches to lock state momentarily during release, then the lock mechanism operates, but the member cannot be adjusted to desired set state
Solution Approach 1:
The hold mechanism performs preliminary action by establishing and maintaining the lock release state before any adjustment operation begins. This preliminary holding ensures that the locking mechanism does not switch to lock state during the adjustment process, allowing smooth member position adjustment while maintaining reliability of the locking function after adjustment is complete.

AI summary
One aspect of the present invention can include a vehicular seat having a first member, a cooperatively moving apparatus configured to release a lock apparatus from being locked in cooperation with a movement of the first member, and a second member configured to be adjusted when the lock apparatus is released. Further, the cooperatively moving apparatus includes a main cooperatively moving member connected to the first member and capable of cooperative movement with the first member, and a sub cooperatively moving member connected to the lock apparatus and capable of being moved by receiving a force from the main cooperatively moving member. Also, a hold mechanism is provided between the main cooperatively moving member and the sub cooperatively moving member, the hold mechanism is capable of holding the lock apparatus in a lock release state by holding a portion of the sub cooperatively moving member by a predetermined amount while operating the main cooperatively moving member. And, when the lock apparatus is maintained in the lock release state, the second member is set to one of a plurality of set states, the lock apparatus is able to be brought into a lock state before and after operating the hold mechanism.
