Abstract

A seat post head assembly is disclosed. The assembly includes a housing coupled to a seat post, the housing including a cylindrical bore, and a first and second threaded chamber. A rotatable core is inserted into and rotates within the cylindrical bore, the rotatable core including a seat rail clamp assembly to fixedly clamp a set of seat rails and provide independent adjustment of a fore-aft location of the seat without affecting a pitch of the seat. The assembly additionally includes a first threaded member that threads into the first threaded chamber, contacts the rotatable core, and adjusts the pitch of the seat without affecting the fore-aft location of the seat. The assembly also includes a second threaded member that threads into the second threaded chamber, contacts a different portion of the rotatable core, and provides a physical hard stop against a change in the pitch.

First claim

What is claimed is:

1. A seat post head assembly comprising:
a seat post, the seat post to couple the seat post head assembly with a seat tube of a vehicle; and
a housing fixedly coupled to the seat post, the housing comprising:
a cylindrical bore therethrough;
a first threaded chamber formed through the housing; and
a second threaded chamber formed through the housing at a location different than the first threaded chamber;

a rotatable core for insertion into the cylindrical bore, the rotatable core being rotatable after insertion into said cylindrical bore, the rotatable core comprising:
a seat rail clamp assembly to fixedly clamp a set of seat rails of a seat and provide independent adjustment of a fore-aft location of the seat without affecting a pitch of the seat;
a first end plate between a first inner seat rail clamp and a first end of the rotatable core;
a second end plate between a second inner seat rail clamp and a second end of the rotatable core, a first threaded member that threads into the first threaded chamber and contacts a first portion of the rotatable core;
the first threaded member to adjust the pitch of the seat without affecting the fore-aft location of the seat; and

a second threaded member that threads into the second threaded chamber and contacts a second portion of the rotatable core,
the second threaded member to provide a physical hard stop against a change in the pitch of the seat.

2. The seat post head assembly of claim 1 further comprising:
a 20 mm offset between an axis of the seat rail clamp assembly and a central axis of a seat post when the first inner seat rail clamp is removably coupled with the first end of the rotatable core and the second inner seat rail clamp is removably coupled with the second end of the rotatable core.

3. The seat post head assembly of claim 1 further comprising:
a 0 mm offset between an axis of the seat rail clamp assembly and a central axis of a seat post when the first inner seat rail clamp is removably coupled with the second end of the rotatable core and the second inner seat rail clamp is removably coupled with the first end of the rotatable core.
