Abstract
A coextruded plastic spring member is disclosed which is bendably disposable between first and second member to create a spring force therebetween. The spring member includes an elongated base formed from a first plastic material which is engageable by the first member. An elongated first spring portion formed from a second plastic material that is resilient and has a predetermined spring characteristic is coextruded with the base member. An elongated second spring portion is coextruded with and extends from the first spring portion and is formed from a third plastic material having a spring characteristic stiffer than that of the first spring portion, with the second spring portion being engageable by the second member. The first and second spring portions are constructed so that the first spring portion is under compressive loading when the second spring portion is bendably engaged by the second member.
