Vehicle Seat Back With Pack Support for Upright Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Military vehicle seats often fail to provide adequate ergonomic support and equipment storage, leading to occupant fatigue and increased risk of back injuries due to rough terrain and kinetic threats.
Innovation Solution
A vehicle seat assembly with an adjustable occupant pack support and ergonomic design, featuring a U-shaped tubular frame, lumbar impact pad, and a vertical adjustment mechanism to accommodate equipment packs, promoting correct posture and reducing weight on the shoulders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional vehicle seats are used without equipment support, then the seat structure remains simple, but occupant fatigue increases and back injuries occur due to improper posture and equipment weight on shoulders
Solution Approach 1:
The patent combines the equipment pack support function with the seat back structure by integrating a shelf into the seat back assembly. This merging of functions allows the seat to simultaneously provide back support and equipment support, improving occupant comfort while avoiding the need for completely separate support structures.
Solution Approach 2:
The seat back assembly is designed to serve multiple functions: providing lumbar support for the occupant's back and simultaneously supporting equipment packs via an integrated shelf. This multi-functionality resolves the contradiction by adding equipment support capability without requiring entirely separate structural elements.
2Adaptability or versatility
If fixed seat designs are used, then manufacturing is simple, but adaptability to different occupants and equipment configurations is limited
Solution Approach 1:
The patent implements adjustability in the seat back assembly, allowing the shelf position to be modified. This dynamic capability enables the seat to adapt to different occupants and equipment configurations, enhancing versatility while maintaining a relatively simple manufacturing process through standardized adjustment mechanisms.

AI summary
A vehicle seat assembly includes a seat bottom, seat back, and occupant pack support. The seat bottom is adapted for use in a substantially horizontal position. The seat back resides adjacent the seat bottom, and comprises a back support surface adapted for use in a substantially upright position. The occupant pack support resides adjacent the back support surface of the seat back, and defines a generally flat inwardly-projecting shelf for vertically supporting an equipment pack carried on a back of an occupant seated in the assembly.
