Vehicle Seat Handle Mechanism for Multi-Function Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle seats with multiple adjustment components often require a large number of actuating means, which can be cumbersome, or they may have a limited number of actuating means despite having various adjustment components, making it difficult for occupants to efficiently adjust the seat functions.
Innovation Solution
A vehicle seat design featuring a handle that unlocks a fitting system allowing adjustable inclination of the backrest, with an adapter and driver mechanism that interacts to lock and unlock the fitting, also actuating a locking device for another adjustment component, reducing the need for multiple actuating means by using a single handle to control multiple functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate actuating means are provided for each adjustment component, then each adjustment function can be independently controlled, but the number of controls increases making the system cumbersome and complex
Solution Approach 1:
The patent combines multiple actuating functions into a single handle mechanism. The handle can be actuated in different directions (first direction for backrest inclination, second direction for lumbar support) to control multiple adjustment components through a unified interface, reducing the number of separate controls while maintaining full adjustment functionality.
Solution Approach 2:
The single handle is designed with multi-functionality to control both the backrest inclination adjustment and the lumbar support adjustment. By enabling one actuating element to perform multiple functions through directional actuation, the system reduces control complexity while preserving adaptability across different seat adjustment needs.
2Device complexity
If a single handle controls multiple adjustment components, then the number of actuating means is reduced, but it becomes difficult to differentiate between different adjustment functions
Solution Approach 1:
The handle's functionality is made dynamic through directional actuation. The handle can be moved in a first direction to control backrest inclination and in a second direction to control lumbar support. This dynamic behavior allows a single static component to provide differentiated control functions based on the direction of user input, maintaining ease of operation while reducing the number of controls.

AI summary
The invention relates to a vehicle seat (1), in particular a motor vehicle seat, with a seat part (3), a backrest (5) whose inclination can be adjusted, at least one fitting (10) for the pivotable mounting of the backrest (5) on the seat part (3). , and a handle (7) for unlocking the fitting (10), wherein an angle of inclination of the backrest (5) can be locked by means of the fitting (10). An adapter (20) is rotatably mounted and coupled to the fitting (10), a driver (30) being arranged between the handle (7) and the adapter (20). The driver (30) interacts with the adapter (20) in a coupled manner in a first direction of rotation (80) for entrainment. A rotation of the driver (30) in the first direction of rotation (80) unlocks the fitting (10). A rotation of the driver (30) in a second direction of rotation (82) actuates a locking device (70) of a further adjustment component of the vehicle seat (1).
