## Abstract

Provided is a pillar trim (30) (a vehicle interior trim) with a main body part (32) formed in a hollow, three-dimensional structure by a thermoplastic synthetic resin. The exterior surface of the main body part (32) has a structure whereby an attachment surface (32a) attached to a vehicle structural member and a design surface (32b) inside the vehicle which are both joined together. In addition, the main body part (32) is formed of a bag-like construction that restricts the flow of internal air to the outside, and the main body part (32) distributes and absorbs impact forces from passenger during vehicle impact by using the internal pressure thereof.

## Claims

### Claim 1

(canceled)

### Claim 2

(canceled)

### Claim 3

A vehicle interior trim that is placed on an interior side of a vehicle structural member, comprising:
a main body part made from thermoplastic synthetic resin and formed in a closed hollow shape restricting the flow of an internal gas to the outside, the main body part having an attachment surface to be attached to a vehicle structural member and a design surface for a vehicle interior;
wherein the entire outer edges of the attachment surface and the design surface are joined together in a sealed manner such that the entire surface of the design surface is configured to absorb impact forces.

### Claim 4 (depends on 3)

The vehicle interior trim according to claim 3, wherein average wall thickness of the main body part is between 0.3 mm and 3.2 mm.

### Claim 5 (depends on 3)

The vehicle interior trim according to claim 3, wherein internal pressure of the main body part is higher than atmospheric pressure.
