Claim 18:
19. A vehicle comprising:
an internal cabin;
one or more seat tracks within the internal cabin;
a seat assembly secured to the one or more seat tracks by one or more securing studs, wherein the seat assembly comprises:
a backrest that is configured to recline over a reclination range; and
a variable reclination range limiter that is configured to selectively adjust a limit of the reclination range,
wherein the reclination range extends between a fully upright position and a fully reclined position,
wherein the variable reclination limiter selectively adjusts the limit of the reclination range to a limited reclination position that is between the fully reclined position and the fully upright position, and wherein the variable reclination limiter prevents movement to the fully reclined position from the limited reclination position,
wherein the variable reclination range limiter is coupled to a recline piston and a pivot axle that defines a pivot point for the backrest, and wherein the variable reclination range limiter comprises:
a stroke-limiting sleeve mounted on a shaft of the recline piston, wherein the recline piston is configured to push and pull with respect to a bracket of the backrest about the pivot axle; and
a securing device coupled to the stroke-limiting sleeve, wherein the securing device passes through a portion of the stroke-limiting sleeve and engages a portion of the shaft of the recline piston to lock the stroke-limiting sleeve in position.
