Vehicle Seat Back Pocket Shield Plate for Easier Object Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seats with back pockets face issues of increased manufacturing costs due to the use of large resin panels and difficulty in storing objects due to interference with internal components, leading to reduced ease of use.
Innovation Solution
A vehicle seat design featuring a flexible shield plate with an extension portion that guides object insertion into the back pocket, preventing interference with internal components and reducing manufacturing costs by eliminating the need for a resin panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a large resin plate member is used to cover the rear surface of the seatback, then the manufacturing cost increases, but the ease of storing objects in the back pocket deteriorates due to interference with internal components
Solution Approach 1:
The backboard is divided into a first backboard (resin plate member) and a second backboard (back skin), where only the necessary lower portion is covered by the resin plate while the upper portion uses the back skin material, reducing material usage and cost while maintaining functionality
Solution Approach 2:
A shield plate is introduced as an intermediary component between the back pocket and the lower-part frame to prevent interference with stored objects, solving the problem of object insertion difficulty without requiring a full resin plate coverage
2Ease of operation
If the back skin is pushed by an object inserted into the back pocket, then the object insertion is facilitated, but the object may be caught by internal components such as the lower-part frame
Solution Approach 1:
The shield plate acts as a mediator between the back pocket and the lower-part frame, preventing direct contact between stored objects and internal components that could cause catching or interference
Solution Approach 2:
The shield plate is pre-positioned to extend upward from the back skin, creating a protective barrier before object insertion occurs, ensuring objects are guided smoothly without encountering internal components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves ease of storing objects in the back pocket while maintaining the seat's appearance and reducing manufacturing costs by using a flexible shield plate that avoids component interference and minimizes noise and deformation.
Implementation Method 1
the shield plate having flexibility includes the extension portion extending upward toward the inner side of the back skin from the connection position with respect to the back skin. Because the upper end of the extension portion is located above the lower-part frame and is not connected to the back skin, when the back skin is pushed by the object inserted into the back pocket, the extension portion of the shield plate is deformed so as to be bent forward, together with the back skin

AI summary
The present invention provides a vehicle seat with improved ease of storing an object in a back pocket. An extension portion of a shield plate extends upward toward the inner side of a back skin from a sewing position with respect to the back skin, and the upper end of the extension portion is located above a lower panel. Thus, when an object S is inserted into a back pocket, the shield plate can restrict the contact between the object and the component such as the lower panel, and the insertion of the object to the deeper part of the back pocket is guided along the shield plate. Thus, ease of storing the object in the back pocket is improved.
