1. A tester for applying forces to a back portion of a vehicle seat, the tester comprising:
- a frame; and
force means connected to the frame for applying isolated forces to the back portion of the seat, the force means comprising;
first force applying means for applying a first force to a first portion of the back portion of the seat wherein the first force applying means is attached to the frame for pivotal movement about a pivot axis; and
second force applying means for applying a second force to a second portion of the back portion of the seat isolated from the first mentioned force wherein the second force applying means is joined to the frame for pivotal movement about the pivot axis independent of the first force applying means during application of the second force.

16. A method of testing deflection of a back portion of a seat, the method comprising:
-
providing a frame with force means connected to the frame for applying two isolated forces to the back portion of the seat, the force means comprising a first force member and a second force member pivotally joined together for independent pivotal movement about a common pivot axis, the two isolated forces being referenced to the common pivot axis; applying the two isolated forces to the seat using the force means, the first force member and the second force member pivoting during application of each corresponding force; and measuring forces applied to the seat and angular displacement of the seat. - View Dependent Claims (17, 18)
