Racing Safety Belt Sewn Ring Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional racing car safety belts pose a risk to pilots in the event of an accident due to the presence of a metal 'D-ring' buckle in the inguinal area, which can cause injury.
Innovation Solution
The safety belt design replaces the metal 'D-ring' with a sewn-on ring structure on the band elements, allowing the inguinal retention band elements to engage with the shoulder strap band elements, eliminating any metal components in the inguinal area and enhancing safety by enabling sliding of the inguinal retention bands within the belt-guide means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal 'D-ring' buckle is used for inguinal retention, then the retention function is achieved, but the safety of the pilot is compromised due to potential injury in case of accident
Solution Approach 1:
The patent removes the metal 'D-ring' buckle from the inguinal area and replaces it with a fabric ring formed by the band element itself. The second end portion of the band element is configured to form a ring that engages with the shoulder strap band elements, eliminating the harmful metal component while maintaining the retention function.
Solution Approach 2:
The patent changes the material parameter from metal to fabric/textile for the ring structure in the inguinal area. This parameter change eliminates the harmful effects of metal while preserving the mechanical function of retention and engagement.
2Reliability
If a fabric ring structure is used instead of metal buckle, then safety is improved by eliminating metal hazards, but the structural complexity increases due to sewing requirements
Solution Approach 1:
The patent merges the ring structure with the band element by forming the ring directly from the second end portion of the band element through sewing. This integration eliminates the need for separate metal components and reduces overall structural complexity while maintaining safety.
Solution Approach 2:
The patent uses fabric/textile materials instead of durable metal components for the ring structure. While fabric may have different durability characteristics, it provides the safety benefit of eliminating metal hazards and can be replaced more easily if needed.

AI summary
Safety belt for racing car comprising: a fastening buckle (2); a first pair (3) of band elements (4d, 4s) having the function of shoulder straps each provided with a first end portion (5) configured to be fixed to the bearing structure of the vehicle and a second end portion (6) provided with a locking tab (7) adapted to couple with the fastening buckle (2); a second pair (9) of band elements (10d, 10s) having the function of the lateral retention of the pilot each provided with a first end portion (11) configured to be fixed to the bearing structure of the vehicle and a second end portion (12) provided with a locking tab (13) adapted to couple with the fastening buckle (2); a third pair (15) of band elements (16d, 16s) having the function of inguinal retention of the pilot each provided with a first end portion (17) configured to be fixed to the bearing structure of the vehicle and a second end portion (18) forming a ring adapted to be engaged by the second portion of the band elements (4s, 4d) having the function of shoulder straps when the first pair (3) of band elements (4d, 4s) are coupled to the fastening buckle (2). A first/a second ring (20,21) obtained by means of a belt portion sewn on the second end portions (12) of the band elements having the function of the lateral retention (10d, 10s) forms a guide for the band elements (16d, 16s) having the function of inguinal retention of the pilot.
