## Abstract

A method of vehicular safety management is disclosed in which a garment or like product is worn by an occupant of the vehicle. The garment includes crushable elements which absorb or dissipate energy on fracture from impact. An article of manufacture is disclosed which is worn by a vehicle occupant during travel and which incorporates component elements which fracture on impact and thereby dissipate collision energy.

## Claims

### Claim 1

A multi-layer fabric structure configured to provide impact protection for a body of a vehicular passenger in a vehicular collision, the fabric structure comprising:
a fabric layer defining a plurality of segmented cellular fabric cavities comprising a matrix arrangement of fabric cells, the matrix arrangement defined by at least one spring;
a friable layer of frangible elements disposed within each of the plurality of segmented cellular fabric cavities;
the frangible elements configured to disintegrate under impact force; and
the plurality of segmented cellular fabric cavities configured to retain the disintegrated frangible elements.

### Claim 2 (depends on 1)

The multi-layer fabric structure of claim 1, wherein the matrix arrangement is formed by joining adjacent fabric cells.

### Claim 3 (depends on 1)

The multi-layer fabric structure of claim 1, wherein the at least one spring is a flat coil spring.

### Claim 4 (depends on 1)

The multi-layer fabric structure of claim 1, wherein the frangible elements comprise at least one of a rigid brittle foam, ceramic and cement.

### Claim 5 (depends on 1)

The multi-layer fabric structure of claim 1, wherein the fabric structure defines a garment configured to be worn on the body of the vehicular passenger.

### Claim 6 (depends on 1)

The multi-layer fabric structure of claim 1, wherein the fabric structure is integral with at least one vehicular safety feature.

### Claim 7 (depends on 6)

The multi-layer fabric structure of claim 6, wherein the fabric structure is integral with a seat belt.
