Vehicle Seat Slider Concealment via Backboard Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle seat designs with metal slider fasteners cause a feeling of a foreign body due to the presence of the metal slider portion, which is noticeable through the covering material, compromising the aesthetic appearance.
Innovation Solution
The end portion of the slide fastener and slider are inserted and locked into an insertion portion on the backboard, positioning them between the seat cover and the slider, thereby hiding the slider and reducing the foreign body sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the end portion of the fastener member and slider portion are disposed on the reverse side of the first covering portion to be invisible, then the appearance of the seat is improved, but the slider portion made of metal plate causes a feeling of a foreign body when felt through the covering material
Solution Approach 1:
The slider portion is extracted from the space between the covering portions and repositioned to the reverse side of the first covering portion. This removes the metal slider from direct contact with the user, eliminating the foreign body sensation while preserving the aesthetic benefit of hiding the fastener mechanism.
Solution Approach 2:
The end portion of the fastener member and slider portion are nested within the reverse side structure of the first covering portion. By tucking these components into the reverse side space, the design achieves both aesthetic concealment and tactile comfort by preventing user contact with the metal slider.
2Reliability
If the slider portion is made of metal plate to ensure durability and functionality, then the fastening mechanism is reliable, but the metal slider causes a feeling of a foreign body when disposed between covering portions
Solution Approach 1:
The metal slider portion is extracted from the user-facing space between covering portions and relocated to the reverse side of the first covering portion. This maintains the metal slider's structural integrity and fastening functionality while removing it from positions where it could be felt by users.
Solution Approach 2:
The first covering portion acts as an intermediary barrier between the user and the metal slider portion. By positioning the slider on the reverse side of this covering portion, the fabric serves as a mediator that blocks tactile contact with the metal, eliminating the foreign body sensation while preserving fastening reliability.

AI summary
A vehicle seat includes a seat pad; a backboard disposed on a back side of the seat pad; and a seat cover covering the seat pad and the backboard. The seat cover includes a pair of covering pieces adjacent to each other on the backboard-side, and a slide fastener that connects the covering pieces. When the slide fastener is closed with use of a slider, an end portion of the slide fastener is projected from an edge end of the seat cover in a state where the slider is disposed in the end portion of the slide fastener. The backboard is provided with an insertion portion. When the end portion of the closed slide fastener is disposed on a reverse side of the seat cover, the end portion of the slide fastener and the slider are inserted in and locked to the insertion portion.
