Definitions
- the present invention relates to a retention and release mechanism providing a safety feature in ski boots. More specifically, the present invention relates to the prevention and mitigation of the severity of injuries to the anterior cruciate knee ligament. This invention also relates to a construction of the ski boot upper to provide a safe biomechanically natural rearward articulation.
- Various prior art devices have been described relating to improving against injury in the sport of downhill skiing. The vast majority of these disclosures relate to improvements in the ski binding; i.e. that mechanism which is affixed directly to the ski. In addition, there have been some disclosures regarding modification to the ski boot itself but more so from the point of view of providing a mechanism for the wearer to more readily step into and out ofthe boot.
- U.S. Patent 5,136,794 there is reported a ski boot consisting of a lower part and of a shaft, in the form of a collar, which is articulated on the lower part and provided with at least one closing buckle.
- the shaft comprises, at the rear, a rocker which interacts with a stop which is integral with the lower part in order to lock the shaft in a position inclined forwards.
- the rocker is held in inactive position upon opening ofthe uppermost buckle by means of a cable and a spring.
- Attention is also directed to U.S. Patent No. 5,127,171.
- a ski boot with a shell comprising a shaft in two parts, the rear part of which is connected, on the one hand, to the shell and, on the other hand, to the front part of the shaft by two pair of links.
- the axis of the articulations on the rear part are situated, in the closed position ofthe boot, on one side and the other of the plane containing the axes of articulation on the shaft and the front part of the shaft. It is possible to open the shaft wide for putting the boot on, while having only a limited tilting backwards of the rear part.
- the upper connection can be associated with a closing lever.
- a ski boot for lessening the incidence of knee injuries which the boot is said to exert a forward directional force on the skier's leg.
- a releasing means changes the rigid support position for the foot and the lower leg on application of a predetermined level of force by the boot on the wearer.
- the '608 disclosure goes on to report thai rearward pressure of the person's lower leg against the rear leg element o the boot can be sensed by force sensors producing electrical outputs by the use of piezoelectric material.
- a mechanical latch assembly employing a tension spring 96 is disclosed, which is described as urging or maintaining the device in ski position, and when said tension is overcome, a release position is obtained as shown in FIG. 8.
- U.S. Patent No. 5,283.964 discloses a boot device for front-to-back immobilization of the upper, which acts on an oscillating level capable of being supported against a stop on the shell base.
- T he device is constituted by a rectilinear- motion control mechanism incorporating an external control device of which an inner pail actuates via a cam a sensing device associated with the oscillating lever so as to impart to the latter an angular rotating movement around its pin toward a locked or release position in relation to the stop formed on the shell base.
- Attention is also directed to following foreign patent documents: WO 92/05718 and 0514762A2. More specifically, in WO 92/0571 there is disclosed a ski boot for enhancing the safety of skiing.
- EP-375-604-A discloses a ski boot with stop holding the leg forward
- French Pateni 2647-649- ⁇ discloses a ski boot with an articulated leg locked in a forward position, which leg is articulated having a clip at the back which pivots around the horizontal axis. All o the above, however, are distinct from the present invention, in that they collectively fail to provide, in the boot itself, a practical mechanism for mitigation of knee injuries while used in skiing.
- the present invention is designed to provide a ski boot that allows the potentially damaging posterior forces at the spoiler (or upper shaft) section of a ski boot 1 to be absorbed or transduced.

Finally, at 88 is illustrated a hinge pin head. and at 90 is shown the flange of 56 that acts to a shoulder to augment the travel limit of spring cap (internal, not shown) against the top of the slot.
- FIG. 7 illustrates in further cross-sectional view the release and retention mechanism, in the ski position, more clearly showing the placement of spring 52. The front of the boot is to the left hand side of the release and retention mechanism shown in FIG. 7.
- FIG. 8 illustrates the release and retention mechanism is release position. Also shown in FIG.
- FIG. 8 at 92 is the contact which occurs as between lower arm linkage and stirrup mounting bracket 74 which further serves to limit travel of the upper arm linkage 54.
- FIG. 9 illustrates at 94 the cutout section of the boot in the stirrup cuff element for placement of the release and retention device herein, at 96 the stirrup pivot point which rivets to the lower shell of the boot, and finally, at 98, one of the screw hole pairs for mounting the stirrup mounting bracket 74.
- FIGS. 10-12 best illustrate in cross-sectional form the release and retention mechanism in both retention and release positions. As illustrated therein, when in ski or retention position, as shown in FIG. 10, the lower arm linkage 56 is urged against the upper shaft 100 of the boot.
- slot 68 reveals in FIG. 10 that 1 when in the ski position, the short hinge pin head 82 is positioned at the top of the slot 68.

- 27 16 illustrates the relationship ofthe arm linkages and the boot upper shaft 106 and boot
- the release and retention mechanism when releases provides a substantially vertical position to the skier. Furthermore, and as noted above, when in release position the rearrangement of the upper and lower arm linkages allows the upper shaft cuff element 106 of the boot to rotate posteriorly at which point it is prevented from further travel by contacting the stationary stirrup 108. The contact point is shown in FIG. 16 at 1 10.
- the present invention therefore relates to a latch element for a retention and release mechanism in a ski boot, comprising a cam thai coacts wilh a stop, said cam being positioned in such a manner that posterior forces imparted by a user urges said cam to disengage from said stop at a predetermined level of posterior force.
- the present invention can also be described as a ski boot containing a retention and release mechanism providing restriction to posterior movement of the upper shaft of said boot and allowing posterior travel of said shaft after a predetermined level of force has been obtained, comprising a latch which contains a plurality of elements that permits compression and change of length when subjected to rearward force by the upper shaft of said boot, said compression and change of length permitted by compression of an elastic spring clement affixed between two mobile elements ( 14) and (3 ), said latch pivotally fixed to point ( 16,17) lhat is radial to the pivotal fixation point o the overall mechanism to the boot shank characterized in that said latch, under a predetermined amount of force, will compress a spring housing element ( 14) until a cam (15) affixed to another spring housing element (2) which urges said cam to dislodge the latch from the slop ( 1 1 ).
- FIG. IA, IB and 1 C represent a front, side, and rear view of the retention and release mechanism of the present invention.
- FIG. 2A and 2B represent an alternative embodiment o the present invention known generally as the hinge carriage assembly.

- FIG. 4A represents the latch of the prior art employed in a ski boot, and
- FIG 4B represents the latch of the present invention, the sidc-by-side comparison emphasizing the differences in the latch and cable housing of the present invention.
- the present invention relates to a retention and release mechanism formed by a cam that coacts with a stop, sad cam being positioned in a manner such that posterior forces imparted to the wearers leg, urges said cam to override or disengage from said stop(s) until the magnitude of force is sufficient to cause the cam to disengage or fully overrun said stop(s) at a predetermined and adjustable level of force.
- the invention also relates to a device to a release and retention mechanism having an adjustable element tat controls the amount of force required to displace a cam to a degree that it fully overrides its coacting stop(s).
- This device comprises a spring or an elastic element and a release mechanism such as a cam or ball spring and socket the exact configuration of which can be various and apparent to those skilled in the art of load specific release mechanisms such as ski bindings and the like
- the invention also relates to a release and retention mechanism offering a secondary elastic function providing sufficient resistance to rearward displacement of the boot shaft to enable the wearer to maintain control of the ski.
- This arrest feature limits the posterior displacement of the boot shaft after the "rear breakoul" or release has occurred.
- An important feature of the present invention is that release or break out is limited.
- the invention also relates to a release and retention mechanism that can be configured to offer a staged release that facilitates repeated compression/deflection of an elastic element, and resetting of a latch mechanism into a series of stop elements or likewise by a series of latch elements coacting with the stop.
- the invention also relates to a retention and release mechanism offerinu sufficient rearward displacement of the boot shaft to increase the tendency of the knee joint of the wearer to extend to a degree that reduces the likelihood that injury to the anterior cruciate ligament of the knee will occur.
- the invention provides the function of absorbing potentially injurious forces before said forces are sustained by the wearer's knee joint.
- An elastic element comprising a means of adjusting preload, acts as a means to urge the interface constraining the boot shaft posteriorly to disengage affecting a posterior "release" to the arrest position. The adjustment governs the level of force or load required to affect release.
- the invention relates to a ski boot having high rearward upper shaft resistance to flex to provide typical performance found in contemporary ski boots until a rearward force approaching that sufficient to damage the knee is encountered whereby the release and retention mechanism will allow the upper boot shaft to freely rotate rearwards for u small distance sufficient to protect the knee yet enable the skier to maintain control of the ski in a new position until the skier can resume a normal forward skiing posture at which point the retention feature of the invention will engage and support the leg posteriorly until the same potentially injurious posterior force level is again encountered.
- the effective moment arm of the ski tail to the knee being shortened increases the likelihood that the skier will fall over the tail of his ski without damaging knee ligaments.
- the present invention describes a ski boot comprising at least one lower foot and heel holding portion with a shaft, in the form of a collar, articulated on the lower part, and comprising connecting means consisting of a latch which interacts with a stop which is integral with the lower part, said connecting means comprising means for fixing or releasing said shaft for rotation relative to the lower part consisting of a cable provided with at least one closing buckle for manuall ⁇ disconnecting said fixation means by pivoting all or a portion of the latch to disengage it from the stop to facilitate upright standing and walking with the boot, including means for automatically disconnecting said latch when an anticipated dangerous level of force is applied to the rear of the shaft by the wearer's leg that comprises an elastic element, a proximal housing which is affixed to the upper shaft, and a distal housing element that is constrained by the proximal housing element in all axis except in compression of the elastic element, a distal element that coacts with the stops that is mobile along the compression axis of the elastic element
- the present invention discloses a ski boot having a pivotally mobile upper shaft, and a lower foot and heel holding portion, that comprises a stop and coacting latch sensing mechanism to allow the upper shaft to further articulate in the rearward direction relative to the Lower foot and heel holding portion under the condition of a force applied to said stop and coacting latch mechanism which urges the latch to disengage from said stop.
- said sensing mechanism preferably comprises a spring and an axially slidable mobile element that coacts with a cam member positioned within said latch that urges a pivotally mobile latch element to cause the latch to disengage from the stop.
- the present invention contemplates the above described retention and release mechanism in a ski boot consisting of a shell surrounding the foot and heel and of a shaft consisting of a front part and of a rear part capable of being tilted towards the rear in order to free the foot and to allow the boot to be put on and off, in which the rear part of the shaft can form a translation movement in addition to a rotation movement, wherein the rear part of the shaft is connected in its lower part to the shell by first means of connection forming axis of articulation with the shell and rear part of the shaft, respectively, which allows a rotation and translation of said rear part in relation to an axis which is defined and fixed in relation to the shell and said upper part of the shaft is connected at another point by a second means of connection, forming an axis of articulation with the front part and rear part ofthe shaft, respectively, which allows a rotation and translation of said rear part in relation to an axis which is defined and fixed in relation to the front part, the axis of articulation for
