Abstract
A safety belt pull-in device comprising a reel having one end of a first safety belt section connected thereto, whereas the other end of the first safety belt section is connectable to a second or stationary belt section. The first belt section, which when not in use, is wound upon the reel, is operatively connected to a motor such as a fluid-operable motor or an electric motor which so controls the reel that when the first safety belt section is being unwound from the reel by pulling the safety belt, is being pulled off the reel at at least nearly even pull.
Claims15
A safety belt pull-in device, especially for land and air vehicles, which includes in combination:
- a rotatable reel comprising a shaft, safety belt means having one end connected to said reel, and being windable upon and off said reel, the other end of said belt means being connectable to a stationary belt, and motor means operatively connected to said reel for winding said belt means onto said reel and permitting a substantially constant unwinding of said belt means off said reel subject to avoiding self-binding during application of only at least approximately even force for permitting withdrawal of said safety belt means.
A safety belt pull-in device, especially for land and air vehicles, which includes:
- a rotatable reel comprising a shaft, safety belt means having one end connected to said reel, and being windable upon and off said reel, the other end of said belt means being connectable to a stationary belt, motor means operatively connected to said reel for winding said belt means onto said reel and permitting a winding of said belt means off said reel at at least approximately even force, said reel having a free end section in the form of a truncated cone provided with thread-like grooves, and flexible pull means forming part of said motor means and having one end connected thereto while its other end is connected to said truncated cone.
