A bicycle saddle construction in which the saddle pan is attached to a one-piece saddle support which underlies and supports the pan. The support includes an upper plate and a downwardly extending skirt, and an intermediate section of the skirt is deformed inwardly to form a downwardly opening socket into which the upper end of a seat post is received and permanently fixed in place by welding.

A plastic saddle comprises a plastic saddle top and a plastic support therefor. The saddle top is gently inclined upward, extends sidewise in width, has a peripheral flange and is provided on its back face with a thick abutting portion in front and two thick abutting portions at rear opposite sides. The support principally comprises two support strips which are spaced apart sidewise by a greater distance at their rear portions than at their upwardly inclined front portions providing an abutment corresponding to the front abutting portion of the saddle top. The rear portions are abruptly inclined upward and are formed at their ends with abutments extending sidewise in facing relation to the rear abutting portions of the saddle top. Extending between the abutments and the outer walls of the support strips are reinforcing plates approximately triangular as seen from the rear. The support strips are interconnected by a deflection preventing plate in the vicinity of the reinforcing plates. The saddle top is supported on the support at three points by face-to-face contact between the corresponding abutting portions and abutments with these parts detachably secured together by connecting means such as bolts and nuts. At an intermediate portion of the support strips means is provided for fixedly mounting the saddle on the seat post at an adjustable angle.

A cycle saddle is disclosed which includes a frame and a plastic cover mounted on top of the frame, with a foam cushion being provided between the cover and the frame. There is disclosed means for securing the cover which includes integrally fused portions of the cover extending through the apertures in the frame to anchor the cover onto the frame. A method is disclosed for producing the cycle saddle which includes the steps of providing a cover provided with a depending skirt having a substantially smooth inner surface portion and provided with a flange integrally attached to said depending skirt at the lower edge thereof having a substantially smooth surface opposing the inner surface portion of the skirt and defining with the inner surface portion an upwardly extending groove, placing the cover on the frame with the depending skirt portions of the frame extending into the groove and with the apertures being disposed in the groove between the inner surface of the flange and the inner surface portion of the skirt, relatively moving the inner surface of the flange and the inner surface portion of the skirt into adjacency through the apertures, and applying ultrasonic means to the skirt and the flange adjacent the apertures for causing portions of the skirt portions and the flange to fuse into integrally fused portions extending through the apertures to anchor the cover onto the frame.

A fiberglass seat shell construction includes plastic inserts which form screw anchors molded in place in protrusions in the lower surface of the seat shell, which inserts have an aperture for threadably receiving self-threading screws which fasten the leg assembly to the seat shell. The inserts have a shank portion which has hexagonal surfaces to prevent rotation of the insert, an upper flange to prevent withdrawal of the insert from the seat shell, and a lower flange which has a planar surface for clamping engagement with the leg assembly under screw pressure and in which the lower flange has a tapered periphery which provides a lead-in surface for proper positioning of the inserts in mold recesses which form the protrusions.
