I need a purpose-built rear-seat restraint that will replace the standard seatbelt in every squad car and safely secure detainees during transport. The unit must use heavy-duty seat-belt–grade webbing or an equivalent textile as the primary material, anchored to the existing seat points or a supplied bracket system. A single-motion quick-release is essential so officers can free the occupant rapidly when protocol demands. The design has to incorporate the following safety features: • Padded restraints to prevent bruising or circulation issues • Certified non-toxic contact materials for skin and clothing • Tamper-resistant locking hardware that cannot be manipulated from inside the vehicle Scope of work 1. Concept sketches and CAD files detailing the restraint layout, anchor hardware, and quick-release mechanism. 2. Material and component specification sheet (webbing grade, buckles, padding, coatings). 3. Prototype or small-batch fabrication ready for field testing, along with an installation guide that fleet technicians can follow. 4. Written compliance notes referencing relevant automotive safety and prisoner-transport standards. Your experience with automotive interior systems, industrial design, or law-enforcement equipment will be highly valued. Please outline any similar products you have delivered and the tools you plan to use (e.g., SolidWorks, AutoCAD, Fusion 360, or equivalent).

This is a safety-critical restraint system and must be engineered to automotive standards, not treated as a simple strap assembly. I can deliver a concept-to-prototype solution focused on structural integrity, rapid officer release, and tamper resistance. Using SolidWorks, I will develop detailed CAD models of the restraint layout, anchor interfaces (existing seat mounts or reinforced brackets), and a single-motion quick-release mechanism positioned out of detainee reach. Load paths will be designed to transfer forces into structural hard points, ensuring durability under dynamic transport conditions. Materials will include automotive-grade, seatbelt-rated polyester webbing, padded restraint zones to prevent bruising or circulation restriction, certified skin-safe contact materials, and tamper-resistant locking hardware. Corrosion-resistant components will be specified for long-term fleet use. Deliverables will include concept sketches, full CAD files, material and hardware specifications, prototype-ready fabrication drawings, and a clear installation guide for fleet technicians. I will also provide compliance notes referencing relevant automotive restraint and prisoner-transport safety considerations. I am ready to review vehicle details and begin development immediately.
