Pivoting Seat Back Hanger for Concealed Bag Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat assemblies lack an efficient and concealed mechanism to hang objects like purses or bags, which can obstruct the seating space and are not effectively supported when unrestrained.
Innovation Solution
A pivotally mounted hanger system integrated into the vehicle seat back, which can extend forward to accommodate objects and retract to a stowed position, hidden between seatbacks, providing a hook-shaped design for secure support and using a spring bias for easy deployment and concealment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed hanger is installed on the vehicle seat, then objects can be hung securely, but the seating space is obstructed and the hanger is always visible
Solution Approach 1:
The hanger is designed to be movable rather than fixed, allowing it to pivot between a deployed position for hanging objects and a retracted position that clears the seating space. This dynamic configuration resolves the contradiction by providing secure hanging capability only when needed, while maintaining clear seating area during normal use.
Solution Approach 2:
The hanger functionality is extracted from a fixed integrated structure and made separable through a pivot connection. This allows the hanger to be removed from the obstructive position when not in use, effectively taking out the interfering element while preserving the hanging function when required.
2Adaptability or versatility
If a hanger is mounted on the seat back, then objects can be hung above the seat base, but the hanger mechanism adds complexity to the seat assembly
Solution Approach 1:
The hanger is designed as a separate, modular component that pivots independently from the seat back structure. This segmentation allows the hanging function to be added without significantly complicating the main seat assembly, as the hanger operates as a distinct element with its own simple pivot mechanism.
Solution Approach 2:
The simple pivot connection provides the necessary adaptability for the hanger to move between positions without requiring complex actuation mechanisms. This dynamic but simple connection resolves the contradiction by adding hanging capability while minimizing the increase in overall system complexity.

Function Achieved in This Case
The hanger system allows for secure and space-efficient hanging of objects above the seat base, maintaining a clear seating area and supporting the load of the objects without obstructing passenger access or visibility when not in use.
Implementation Method 1
a spring biasing the hanger to the stowed position

AI summary
A vehicle seat assembly is provided that includes a seat base, a seat back coupled to the seat, and a hanger pivotally mounted to an upright side wall of the seat back. The hanger pivots forward to a use position in front of the seat back and above the seat base and pivots upward to a stowed position.
