A pair of roller wheels at the head end and a pair at the foot end of the carriage support the platform. A single common axle supports the head end pair of rollers from the carriage, forms a pivot support for the folding shoulder stops, and forms part of an adjustable position support assembly for the headrest. The shoulder stops are preferably attached to a tubular sleeve that rotates on the common axle. ## Claims ### Claim 1 A reformer exercise apparatus comprising: a generally rectangular frame having a head end, a foot end and a pair of spaced apart parallel track members therebetween; a movable carriage mounted on the rectangular frame for movement along the track members between the head and foot ends; the carriage having a carriage frame with a pair of spaced rollers mounted on a common single axle at a head end thereof, wherein each roller is positioned to roll on one of the tracks; a pair of spaced shoulder stops fastened to the carriage; a headrest fastened to the carriage frame between the shoulder stops, wherein the headrest is supported by the axle; and plurality of elongated elastic members extending between the carriage and the foot end of the rectangular frame for biasing the carriage toward the foot end of the frame. ### Claim 2 (depends on 1) The apparatus of claim 1 wherein the shoulder stops are rotatably mounted on the common axle. ### Claim 3 (depends on 2) The apparatus of claim 2 further comprising a tubular sleeve on the axle extending between the rollers wherein at least one of the shoulder stops is fastened to the tubular sleeve. ### Claim 4 (depends on 1) The apparatus of claim 1 wherein the headrest has a notched support member extending therefrom engaging the axle to provide a plurality of headrest support positions above the carriage frame. ### Claim 5 (depends on 1) The apparatus according to claim 1 wherein the carriage frame comprises a pair of parallel spaced channel members and the axle passes through each of the spaced channel members to support one of the head end roller wheels in each channel member. ### Claim 6 A carriage assembly for use on a reformer exercise apparatus having a pair of parallel spaced tracks such that the carriage assembly may be moved back and forth on the tracks, the carriage assembly comprising: a carriage frame with a pair of spaced rollers mounted to a common axle extending across the head end of the frame, wherein each roller is positioned to roll on one of the tracks; and a head rest at the head end of the frame at least partially supported by the common axle. ### Claim 7 (depends on 6) The carriage assembly according to claim 6 wherein the frame has a pair of spaced parallel channel members and the common axle extends through both channel members with one of the rollers in each channel. ### Claim 8 (depends on 6) The carriage assembly of claim 6 wherein the headrest has a notched support member extending therefrom supported by the axle providing a plurality of headrest support positions above the carriage frame. ### Claim 9 A carriage for use in a reformer exercise apparatus having a pair of parallel spaced tracks for supporting the carriage for movement back and forth on the tracks, the carriage comprising: a generally rectangular carriage frame having a pair of parallel channel members spaced to operably ride on the tracks, the carriage frame having a pair of rollers at a head end thereof mounted on a common axle passing through the channel members and supporting the head end of the frame; and a head rest mounted on the carriage frame, wherein the head rest is partially supported by the common axle. ### Claim 10 (depends on 9) The carriage of claim 9 wherein the headrest has a notched support member extending therefrom engaging the axle to provide a plurality of headrest support positions above the carriage frame.
