SINGLE-LAYER PADDING SYSTEM

摘要

An impact-absorbing padding system made of a single-layer thermoplastic polyurethane sheet. The bottom of the sheet is flat, and the top side is also flat and has multiple, spaced apart projections. The projections are frustaconal in shape, having a flat top side and an open bottom. At least some of the projections are connected by ribs. The number and height of the ribs varies to achieve variable hardness within the system.
