Integrated foam type headrest having different hardnesses, and manufacturing method thereof

Abstract

The present invention relates to an integrated foam type headrest and a manufacturing method thereof. The headrest comprises: a headrest cover; a cushion member which is attached to the inside of the cover before forming foam of a foaming member, and is made of material having high elongation and low resistant elasticity; a partition member, attached to the inside of the cushion member, for preventing the foaming member from penetrating the cushion member; a stay frame for fixing the headrest to a sheet; and a foaming member which surrounds the stay frame and is filled in the inside of the cover of the headrest by means of foam-forming. Accordingly, even though a cushion member having a thickness of 10 mm or more is installed to satisfy the softness property of the headrest, the cushion member can be stably adhered to the cover, and can be reliability installed even at a bending part. Furthermore, sewing convenience is achieved, and thus mass production is possible.

Description

technical field [0001] The present invention generally relates to integral foam head restraints. More particularly, the present invention relates to an integral foam type headrest having portions of different hardness and a manufacturing method thereof, wherein a cushion portion and a main body of the headrest may be manufactured in an integral foam type to provide a headrest having portions of different hardness. Background technique [0002] Generally, the head restraint is designed to be installed on the driver's seat and the passenger seat of the vehicle, and is used to support the driver's or passenger's head so that the head can be rested on, while preventing the Tilt back and forth. [0003] In conventional headrests, the headrest is manufactured as a skin material sewn with fabric having air permeability by inserting or injecting flexible polyurethane, which is a foam material excellent in cushioning properties. Such as figure 1 As shown in , this headrest is made...

AI Technical Summary

Problems solved by technology

However, there is a problem that since the part on which the user's head rests has the same hardness as other parts, the user's stability and comfort are reduced

However, there is a problem that processing after foaming, such as decorating the foamed headrest main body, cutting the main body, inserting the cushion member, attaching the strip to the cushion member, etc., takes a lot of time and expense

However, in this case, as Figure 5 As shown in , the sponge for preventing adsorption presses the cushion member at the curved portion of the headrest, thereby causing creases B, so the softness at creases B is significantly reduced, and the occupant feels Uncomfortable, which leads to problems in mass production and quality deterioration of headrests
