  • Patent number: 9050991
    Abstract: A strap adjuster is adapted for use with a strap, and includes a housing permitting passage of the strap therethrough, a strap-guiding member disposed in the housing, and a locking member disposed in the housing and cooperating with the housing to define a locking area therebetween. The housing permits the strap to enter therein in an entry direction. The strap-guiding member guides the strap to change from extending in the entry direction to extending in an exit direction. The locking area permits the strap extending in the exit direction to pass therethrough. The locking member is operable for restricting movement of the strap, and the housing further permits the strap passing through the locking area to exit therefrom.
