Pivotable Seat Units for Side-Accessible Cargo Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle cabins face challenges in providing both high seating comfort and safety while allowing easy side loading, as previous designs either compromise on occupant protection or result in uneven, inaccessible loading spaces.
Innovation Solution
The design incorporates detachably anchored lateral vertical beams and cam mounts for secure locking, along with adjustable seat units that pivot inward to form a level loading area, ensuring strength, rigidity, and accessibility from the side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If seats are designed for high comfort and safety with fixed positions, then occupant protection is improved, but side loading capability deteriorates
Solution Approach 1:
The seat units are designed with dynamic positioning capability, allowing them to be固定在safe positions during travel and moved to side positions during loading. The pivotable seat panels and adjustable backrests enable the cargo space to be accessible from the side while maintaining structural integrity and safety features during operation.
2Reliability
If seats are designed for high comfort with fixed positions, then seating comfort is improved, but conversion to loading space deteriorates
Solution Approach 1:
The seat units feature dynamically adjustable components including pivotable seat panels about a first pivot axis and backrests that can be positioned at various angles. This allows the seats to provide comfortable fixed positions during travel and easily convert to form a level loading platform when pivoted to the side position, maintaining both comfort and versatility.
3Adaptability or versatility
If seats are made pivotable to enable side loading, then side loading capability is improved, but structural strength deteriorates
Solution Approach 1:
The seat units are segmented into separate pivotable components (seat panels, backrests, headrests) that can independently move to side positions. This segmentation allows the loading function to be achieved without compromising the overall structural strength of the cabin frame, as each component is designed to pivot while maintaining structural integrity.
4Ease of operation
If seats are made pivotable to form loading platform, then loading accessibility is improved, but seating comfort deteriorates
Solution Approach 1:
The seat units incorporate dynamically adjustable components including pivotable seat panels and backrests with multiple positioning options. During travel, the seats can be configured in comfortable fixed positions, and during loading operations, they can be pivoted to form an accessible loading platform, thus providing both comfort and ease of operation at different times.

AI summary
The cargo cabin of a motor vehicle for transporting personnel and equipment has a cabin frame (2) formed by longitudinal and transverse beams, designed for a removable cabin shell, and a cabin interior with two rows of seats facing each other in the direction of travel and running laterally above a central vehicle floor. These seats have bench panels (59) and backrests (56) connected to each other via a first pivot axis (79). The bench panels (5) together with the backrests (56), forming a loading platform, can be pivoted inwards about a second pivot axis (65), so that the cargo cabin can be converted into a side-accessible cargo space for transporting equipment. Each bench panel (59) has a seat (55) designed for one person, and each seat is assigned a backrest (56) with seat belts (58) and a headrest (57).Each backrest (56) can be lowered towards the seat body (55) by means of a lowering mechanism (18) and is locked with side beams (25) which are detachably anchored in the cabin frame (2).
