Portable Belt Locking Member for Interrelated Loop Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor coaches and mass transportation vehicles are not required to have seat belts, making passengers prone to injuries from rollovers and collisions due to their high center of gravity, and existing safety solutions are not easily portable or effective.
Innovation Solution
A portable safety belt with an adjustable closed loop and open loop design, featuring a locking member with a clamping section and receiving section, and a reinforcing member to provide secure and adjustable restraint, fabricated using strong materials like ballistic nylon or Kevlar, which can be easily anchored and adjusted for use in motor coach seats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a portable safety belt is provided for motor coaches, then passenger safety is improved, but the complexity of the restraint system increases
Solution Approach 1:
The safety belt system is divided into separate functional components: a locking member with clamping section and receiving section, an adjustable closed loop portion, and an adjustable open loop portion with buckle. This segmentation allows each component to perform its specific function independently, making the overall system more manageable and easier to use while maintaining high safety standards.
Solution Approach 2:
The safety belt incorporates adjustable mechanisms that allow the closed loop and open loop portions to be dynamically resized to fit different passengers and seat configurations. The locking member enables easy adjustment of the belt configuration without requiring complex tools or procedures, thus improving safety while keeping the system user-friendly.
2Adaptability or versatility
If the locking member provides interrelated lockable size adjustment, then adaptability is improved, but the device complexity increases
Solution Approach 1:
The locking member combines multiple functions into a single integrated component: it provides locking action, size adjustment for both closed and open loops, and structural support. The clamping section and receiving section work together as a unified mechanism, eliminating the need for separate adjustment devices and reducing overall system complexity while maintaining high adaptability.
Solution Approach 2:
The locking member is designed as a multi-functional component that can adjust and lock both the closed loop portion (for seatback attachment) and the open loop portion (for passenger restraint). This universal design allows a single mechanism to handle multiple adjustment requirements, improving versatility without proportionally increasing complexity.
3Ease of operation
If the clamping section receives the belt strap through multiple openings, then ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The clamping section and receiving section are pre-configured with openings positioned at optimal locations during manufacturing. The strap routing path is designed in advance with clearly defined entry and exit points, allowing users to easily thread the strap through the correct openings without requiring complex alignment procedures during installation or adjustment.

AI summary
A portable safety belt for use on a motor coach passenger seat is provided. The portable safety belt is formed of a single strap routed to form a closed loop for encircling a seatback and an open loop terminating at either end of the strap with a male and female buckle. The open loop is adapted as a lap belt for holding a passenger. A locking member disposed at a side of the closed loop provides interrelated adjustment of the open and closed loops to tighten the closed loop around the seatback.
