A sport shoe, such as a ski boot, has a rear shaft part which can be pivoted backwards for putting on the ski boot. On this rear shaft part a tensioning device for a band is arranged, which band is anchored by means of its two ends on a front shaft part. The tensioning device has a take-up drum for the band which is connected to a drive shaft via a shiftable splined coupling. To rotate the drive shaft, a tensioning lever which can be pivoted to and fro, is connected to the drive shaft by a grip-roller freewheel coupling. A return rotation of the drive shaft is prevented by means of a return lock. The drive shaft and the return lock are accommodated in a housing which is displaceable, in its longitudinal direction, in relation to the rear shaft part. To release the take-up drum for the purpose of unwinding the band, the splined coupling is uncoupled by displacing the housing in relation to the take-up drum which is held in its position by a support bar.

Ski boot with a rear closing device

On the shaft (14) of the ski boot (12), a spindle (40) is mounted in the heel area (10). The spindle runs parallel to the sole (16) and at right angles to the longitudinal direction (B) of the boot. On the spindle (40), two opposite-running threads (38, 38') are formed, on each of which a support member (32) is located. By means of rotation of the spindle (40) from outside the ski boot (12), the support members (32) are moved towards or away from one another. This relative movement of the support members (32) is transformed, via inclined surfaces (30) on support ribs (26) of the foot-bed (22), into a movement of the foot-bed (22) in the direction of the arrow (A). By means of an asymmetrical arrangement of the two support members (32) in relation to the longitudinal center plane of the boot, a transverse inclination of the foot-bed (22) can be set.
