Multidirectional Vehicular Seat Control via Segmented Motor Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicular seat control apparatuses are limited to vertical and anteroposterior adjustments, failing to accommodate varying passenger body sizes and traveling environments, restricting the ability to achieve multiple orientations of the seat.
Innovation Solution
A multidirectional control apparatus for vehicular seats, incorporating a seat cushion frame with motors and support links arranged in anteroposterior and oblique configurations, allowing for anteroposterior tilting, lateral tilting, and height adjustments through a system of rotational links and ball joints, enabling various orientations based on passenger size and environment.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional seat control apparatus with limited directional adjustment is used, then device complexity is reduced, but adaptability to different passenger body sizes and traveling environments deteriorates
Solution Approach 1:
The seat control apparatus is divided into multiple independent motor units (first motor for anteroposterior tilting, second motor for lateral tilting, third motor for height adjustment) that can operate independently or in combination. Each motor unit has its own drive mechanism and control system, allowing the seat to achieve complex multidirectional movements through coordinated action of segmented components rather than a single complex mechanism.
Solution Approach 2:
The seat control apparatus is designed to perform multiple functions using a unified system architecture. The same basic mechanism structure (motor + rotational link + support link) is used for different adjustment functions (anteroposterior tilting, lateral tilting, height adjustment), making the system versatile and adaptable to various passenger needs and traveling environments while avoiding the need for separate specialized mechanisms for each function.
2Adaptability or versatility
If multiple motors and rotational links are added for multidirectional control, then adaptability and orientation control are improved, but device complexity increases
Solution Approach 1:
The rotational links are designed with asymmetric connection configurations - the first rotational link connects for anteroposterior tilting, while the second and third rotational links are arranged symmetrically for lateral tilting. This asymmetric design allows each motor unit to achieve its specific directional control function efficiently without requiring identical complex mechanisms for all directions, reducing overall structural complexity while maintaining multidirectional adaptability.
Solution Approach 2:
The patent transitions from conventional single-dimensional (vertical) or two-dimensional (vertical + anteroposterior) seat adjustment to three-dimensional multidirectional control by adding lateral tilting capability. The second motor unit introduces a new dimensional degree of freedom (lateral direction) that works in conjunction with the existing anteroposterior and vertical adjustment mechanisms, enabling the seat to achieve complex spatial orientations through coordinated movement in multiple dimensions.

AI summary
A multidirectional control apparatus for a vehicular seat is provided to perform anteroposterior tilting, lateral tilting, control of height and tilting in other directions in consideration of the body size of a passenger and the traveling environment. The multidirectional control apparatus improves passenger comfort by tilting the seat in a lateral direction when entering or exiting a vehicle, prevents the passenger from leaning to one side by tilting the seat in a lateral direction during turning of the vehicle, and offers a safety function of protecting the passenger by inclining the seat in the direction of a collision in the event of a collision of the vehicle.
