Bidirectional Motor Vehicle Seat With Sliding Backrest Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor vehicle seats are limited to supporting occupants only in a forward-facing direction, lacking the ability to easily convert for rearward-facing use, which can be advantageous in certain applications.
Innovation Solution
A motor vehicle seat design featuring a backrest part that can be moved between two translational positions via a sliding mount, allowing the seat to be used in both forward and rearward directions, with lateral sections providing support and a pivot mechanism for adjusting the backrest surface orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the backrest part is made fixed in a single position, then the structural complexity is reduced, but the adaptability for different seating directions is lost
Solution Approach 1:
The backrest part is made movable relative to the seat part through a sliding mount mechanism, allowing it to be repositioned between forward-facing and rearward-facing orientations. This dynamic configuration enables the seat to adapt to different seating directions while maintaining a relatively simple structural implementation.
2Adaptability or versatility
If the backrest part is moved to provide rearward-facing seating, then the versatility is improved, but the lateral support for occupants may be compromised
Solution Approach 1:
The backrest part is divided into a central section and two lateral sections. The lateral sections are positioned closer to the front and rear edges of the seat part respectively, providing targeted lateral support for occupants in both forward-facing and rearward-facing positions. This localized structural arrangement ensures adequate support in each orientation.
3Reliability
If additional lateral space is allocated for support structures, then the lateral support is improved, but the installation space requirement increases
Solution Approach 1:
The lateral support sections are integrated into the backrest part structure itself, combining the backrest function with lateral support function. This merging eliminates the need for separate lateral support structures that would require additional lateral space, as the lateral sections of the backrest provide both back support and lateral stabilization.
4Ease of operation
If the backrest part is made movable for direction conversion, then the ease of operation is improved, but the locking reliability for safe seating may be reduced
Solution Approach 1:
The sliding mount mechanism allows the backrest part to be easily repositioned between forward-facing and rearward-facing positions while incorporating a locking mechanism that ensures stable and secure positioning in each orientation, balancing ease of operation with positioning reliability.

AI summary
A seat for a motor vehicle includes a backrest part with a front side and rear side facing away from the front side. A backrest surface, which serves for supporting a back, is transversely divided into a central section and two lateral sections. A seat part includes a sliding mount for the backrest part to realize a translational motion of the backrest part relative to the seat part between a forward facing position and a rearward facing position. Two lateral sections form a lateral support for a person on the seat and/or the seat part as a two-piece seat part including a first section and a second section and an intermediate space. A bracket extends through the intermediate space.
