Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side protection adjusting devices for vehicle seats are structurally complex, leading to assembly difficulties and inefficiencies.
Innovation Solution
A side protection adjusting device with a simple structure, comprising a side plate, a covering element, a limiting assembly, a fixing assembly, an air cushion, and a rotating assembly, where the air cushion's inflation and deflation states control the rotation of the covering element to adjust the side protection's angle, enhancing the covering effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing side protection adjusting devices are used, then the side protection angle can be adjusted, but the device structure becomes complicated and assembly becomes difficult
Solution Approach 1:
The patent combines the limiting assembly, fixing assembly, air cushion, and rotating assembly into an integrated side protection adjusting device. The limiting plate and connecting plates form a unified limiting assembly that guides rotation, while the fixing assembly integrates multiple fixing portions and positioning plates into a single structural unit. This merging of components reduces overall device complexity while maintaining the angle adjustment function.
Solution Approach 2:
The device is divided into distinct functional modules: the limiting assembly (limiting plate, connecting plates) that defines rotation boundaries, the fixing assembly (fixing portions, positioning plates) that secures components, the air cushion that provides actuating force, and the rotating assembly that executes the angle adjustment. This segmentation allows each module to be independently designed and assembled, simplifying the overall assembly process.
2Adaptability or versatility
If existing side protection adjusting devices are used, then the side protection angle can be adjusted, but assembly difficulties increase
Solution Approach 1:
The limiting assembly and fixing assembly are pre-configured with specific geometries and connection features before final assembly. The limiting plate is pre-formed with connecting plates attached, creating a ready-to-install limiting assembly. Similarly, the fixing portions and positioning plates are pre-positioned to facilitate straightforward mounting onto the side plate, reducing assembly complexity.
Solution Approach 2:
The air cushion serves as an intermediary actuator between the control system and the rotating assembly. Instead of directly mechanical linkages, the air cushion translates pneumatic pressure into rotational motion of the covering element, simplifying the mechanical transmission path and easing the assembly process.

Function Achieved in This Case
The device simplifies the assembly process, enhances production efficiency, and effectively adjusts the side protection's angle to improve the seating comfort by providing a more efficient and user-friendly mechanism for enhancing the covering effect.
Implementation Method 1
An air cushion is provided between the pressing plate and the pressing rod so as to drive the pressing rod to rotate towards an inner side of the backrest through an operation of the air cushion

AI summary
A side protection adjusting device for a seat is disposed at a side protection portion of a seat. The side protection portion includes a side plate and a covering element covering the side plate. The device includes a limiting assembly disposed on the side plate and forming an operative space in between with the side plate, a fixing assembly for securing the limiting assembly on the side plate and including an axial portion, an air cushion arranged in the operative space and having an inflated state and a deflated state, and a rotating assembly axially disposed on the axial portion. Thus, the rotating assembly has a rotating state in which the covering element is driven to rotate while the air cushion is becoming the inflated state, and an initial state in which a position of the rotating assembly is restored while the air cushion is becoming the deflated state.
