| 摘要 |
A seat operated parking brake assembly for lift trucks and the like normally imposes an overload force on a caliper-type brake thereof, after the brake has been engaged. The present invention provides an arrangement (34 or 34') for maintaining a brake (20) of this type in its disengaged condition when a seat (11) is maintained in a first position under the weight of an operator and for isolating continued movement of the seat (11) from the brake (20), after the brake (20) has been engaged in response to initial movement of the seat (11).
