VEHICLE SEAT HEADREST AND METHOD FOR PRODUCING SAME

Provided is a headrest that facilitates the assembly of a structural member for absorbing impact, and a method for producing the same. The method for manufacturing the headrest having surface material 12, headrest stay 13, seal 17 sealing an opening at the bottom of headrest 11, plate-like impact-absorbing member 18, one end of which is connected to seal 17, and foamed body 19 in headrest 11 includes a step of inserting headrest stay 13 in insertion holes 23a and 23b of seal 17 and assembling it, a step of inserting headrest stay 13 and impact-absorbing member 18 through the opening, a step of inserting a circumferential portion of the opening of surface material 12 into seal 17, a step of injecting a foaming material through injection hole 25 of seal 17 and foaming it, and a step of forming a foamed body by curing the injected foaming material.
