Vehicle Seat Sensor Attachment Structure for Flexible Cushion Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing seating sensors for vehicle seats are difficult to attach to soft cushion portions due to their flexible film nature, leading to instability and increased man-hours in attachment, with a risk of disconnection during the process.
Innovation Solution
A film-like seating sensor with a holding member that includes facing wall portions and a connection portion, which can be received in a concave portion of the cushion, providing protection and stability, allowing easy attachment and preventing disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seating sensor is made as a flexible film to adapt to the cushion shape, then the sensor can conform to the cushion surface, but the sensor becomes difficult to attach stably and requires more man-hours
Solution Approach 1:
The seating sensor is divided into multiple independent adhesive sections that can be attached separately to the cushion surface. This segmentation allows each section to be positioned and secured independently, improving overall attachment stability while maintaining the flexible film's ability to conform to the cushion shape.
Solution Approach 2:
Positioning marks are provided on the seating sensor to guide the attachment process. These marks enable workers to quickly and accurately position the sensor before attachment, reducing the time and effort required for installation while ensuring proper alignment and stable attachment.
2Adaptability or versatility
If the seating sensor is made as a flexible film, then the sensor can adapt to the cushion, but the sensor may be bent at acute angles during attachment causing disconnection
Solution Approach 1:
Protective structures are incorporated into the seating sensor design to prevent acute angle bending during attachment. These protective features cushion the sensor against excessive deformation, ensuring that the flexible film maintains its integrity and electrical connections remain stable even when conforming to the cushion surface.
3Ease of operation
If the seating sensor is attached to a soft cushion portion, then the sensor can be installed in the intended location, but the attachment becomes troublesome and unstable
Solution Approach 1:
The sensor is divided into multiple adhesive sections that can be pressed onto the cushion in stages. This segmentation allows the soft cushion material to be gradually compressed and conform to the sensor, creating a stable attachment while maintaining ease of installation.
Solution Approach 2:
Positioning marks are provided on the seating sensor to indicate correct placement. These visual guides simplify the attachment process by showing workers exactly where to position and press the sensor onto the cushion, ensuring stable attachment while reducing installation complexity.

AI summary
Provided are a seating sensor for a vehicle seat and an attaching structure therefor that make it possible to easily attach the seating sensor to a cushion portion. For that purpose, the sensor comprises a film-like main body 21 with flexibility adapted to be laid, between a surface on a seating side of a pad member 13 with a concave portion 15 and a skin member 14, across the concave portion and having a plurality of detecting sections 21 a for detecting a passenger seating on the pad member in contact with the surface on the seating side of the pad member, an output section 21 b, and a continuity section 21 c; and a holding member 30 configured to curve and hold a part of the continuity section constituting region of the film-like main body and to be able to be received together with the curved continuity section constituting region in the concave portion and having a pair of facing wall portions 30a, 30b facing inside surfaces of the concave portion and a connection potion 30c connecting respective one ends of the facing wall portions for enabling the facing wall portions and the connection portion to cover at least one side surface of the curved continuity section constituting region 31 c.
