摘要： A seat back of vehicle seat including: a seat back frame; a support wire element disposed in the seat back frame; a support plate attached to the support wire element such that an upper portion thereof projects upwardly from the support wire element; and a resilient reinforcing element provided to that upper portion of support wire element, thereby normally reinforcing such upper portion. The resilient reinforcing element has two upper end portions respectively slidably engaged with two brackets of the seat back frame and a main reinforcing portion which is resiliently extensible, while being resiliently deformable rearwardly of the seat back frame. Another resilient reinforcing element having a pair of reinforcing portions may be provided to a lower portion of the support wire element to normally reinforce such upper portion. Each of those two different reinforcing elements is resiliently deformable rearwardly by an excessive great load applied thereto.
