Vehicle Seat Cargo Divider With Tensioned Wires for Lateral Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo dividers in vehicles only provide protection in the forward direction when backrests of the back seat are folded down, leaving passengers susceptible to danger from cargo in case of accidents or sharp turns.
Innovation Solution
A cargo divider system comprising first and second structure parts with attached wires, where the wires are stretched via biased rollers to maintain tension regardless of the folding angle between the backrests, providing protection in both forward and lateral directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extractable cargo dividers are placed in cassettes at the top of the backrests, then the cargo divider can be extracted to cover the opening between the backrests and the luggage compartment, but the cargo divider only provides protection in the forward direction and not in the lateral direction when backrests are folded down
Solution Approach 1:
The cargo divider is divided into multiple independent wire elements (first wire, second wire, third wire, fourth wire) that can be individually tensioned and positioned. Each wire segment can independently provide lateral protection, allowing the system to adapt to different backrest folding configurations while maintaining comprehensive cargo containment.
Solution Approach 2:
The patent transitions from a single-plane cargo divider (forward direction only) to a multi-dimensional wire network structure. The wires are arranged in both longitudinal and lateral directions, creating a three-dimensional cargo containment space that provides protection in multiple directions simultaneously when backrests are folded down.
2Device complexity
If the cargo divider uses fixed wire structures, then the structure is simple, but the wires cannot maintain proper tension when the relative folding angle between backrests changes
Solution Approach 1:
The wire structure incorporates dynamic adjustment mechanisms including biased rollers and adjustable tensioning devices that allow the wire lengths and tensions to be modified based on the backrest folding angle. This dynamic adaptability ensures that the cargo divider maintains proper tension and effectiveness regardless of the relative positions of the folded backrests.
Solution Approach 2:
The patent enables changes in wire tension and wire length parameters according to the backrest folding configuration. The biased rollers automatically adjust wire tension based on the folding angle, while adjustable tensioning devices allow manual parameter optimization to maintain reliable cargo containment under varying geometric conditions.
3Device complexity
If the cargo divider protects only in the forward direction, then the device complexity is low, but passengers sitting in the backseat next to folded down backrests are susceptible to danger from transported cargo in case of accident or sharp turns
Solution Approach 1:
The protection system is segmented into multiple wire elements positioned at different locations (first wire at top, second wire at middle, third wire at bottom of first backrest; fourth wire at top, fifth wire at middle, sixth wire at bottom of second backrest). This segmentation allows each wire to independently prevent cargo movement in specific zones, providing comprehensive lateral protection while maintaining manageable system complexity.
Solution Approach 2:
The wire-based cargo divider system serves multiple functions simultaneously: it provides forward direction protection, lateral direction protection, and adjustable adaptation to different backrest configurations. This multi-functionality addresses the harmful factor of cargo shifting in all directions without requiring separate protection systems for each direction.
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
The cargo divider effectively protects passengers from cargo shifting during transport, ensuring safety even when only some backrests are folded down, while also preventing cargo from shifting laterally.
Implementation Method 1
The first ends of each of the first wire and the one or a plurality of further wires are attached to the first structure part via a separate first biased roller so that each of the first wire and the one or a plurality of further wires are stretched at all times regardless of a relative folding angle between the first structure part and the second structure part

AI summary
A cargo divider between a first vehicle seat backrest and a second vehicle seat backrest used when one of the first or second backrest is folded down. The divider includes a first structure part along a lateral edge of the first backrest adjacent the second backrest, including a first top section, a first middle section and a first bottom section; a second structure part arranged along a lateral edge of the second backrest adjacent the first backrest, including a second top section, a second middle section and a second bottom section; a first wire having a first end attached to the first top section and a second end attached to the second top section; one or a plurality of further wires including a first end attached along the first middle section and a second end attached correspondingly along the second middle section.
