Vehicle Seat Guide Mechanism for Rear-Entry Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle seats require complex structural adjustments to transition between a usage position and an entry position, complicating access to rear seats.
Innovation Solution
A motor vehicle seat design utilizing a guide mechanism with a first and second guide track and pins, allowing translational and rotational movements to simplify the adjustment between operating and entry positions, facilitated by a cam mechanism and locking arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a seat cushion is divided into a seat cushion base and a seat cushion insert that can be moved independently of one another, then the seat cushion can be adapted to different seating positions and individual requirements, but the device complexity increases
Solution Approach 1:
The seat cushion is divided into two independent parts: a seat cushion base and a seat cushion insert. The insert can be moved independently along the longitudinal axis relative to the base, allowing adaptation to different seating positions without requiring a completely new cushion design. This segmentation enables versatile adjustment while keeping each component relatively simple.
Solution Approach 2:
The seat cushion insert is designed to be movable rather than fixed, allowing dynamic adjustment along the longitudinal axis. This dynamic capability enables the cushion to adapt to different user requirements and seating positions, transforming a static component into an adaptable system.
2Device complexity
If a seat cushion is designed as a single piece, then the device complexity is low, but the adaptability to different seating positions and individual requirements is limited
Solution Approach 1:
Rather than using a single-piece design, the cushion is segmented into movable components (base and insert) that can be independently positioned. This segmentation adds adaptability while keeping each individual component relatively simple in structure.
Solution Approach 2:
The movable insert design allows a single cushion assembly to serve multiple functions and adapt to different user needs and seating positions, replacing the need for multiple different cushion designs for different applications.

AI summary
The invention relates to a motor vehicle seat, comprising a slotted guide and a seat structure that has a seat element and a backrest. The seat structure is adjustable from a use position, in which the seat element extends approximately horizontally, via an intermediate position to an entry position, in which the seat element is inclined with respect to the horizontal. By means of the slotted guide, the seat structure is guidable such that the seat structure is translatable from the use position as far as the intermediate position and is rotatable from the intermediate position as far as the entry position.
