Combat vehicle restraint system
View Patent ↗A combat vehicle restraint system accommodates a wide range of soldiers, both with and without battle, arctic, or chemical gear. The restraint system includes lengthened belts and an adjustable buckle position. The belts include loops for locating and grasping the belts, and separate lap and shoulder belts with small narrowing ends to prevent catching on gear. The belts are extendable from Inertial reels which are calibrated for off-road operation. The buckle engages each belt separately and includes a single action release. The buckle position is easily adjusted using an oversized knob so that a soldier may easily find and adjust buckle length in the dark, wearing heavy gloves, or with muddy slippery fingers. The latch/unlatch mechanism and associated hardware is an open frame type to reduce or eliminate affects of mud, dust, water or other contaminants on operation.
1. A restraint system comprising:
a shoulder inertial reel;
a shoulder belt extendable from the shoulder inertial reel and having a shoulder connector;
a lap inertial reel;
a lap belt extendable from the lap inertial reel and having a lap belt connector;
a buckle mount connected to a vehicle;
a buckle adjuster connected to the buckle mount, the buckle adjuster comprising:
an arm having a mount end and a latch end, the mount end attached to the buckle mount;
a latching mechanism fixedly attached to the latch end of the arm; and
a longitudinal slide having a stop end and a buckle end and at least two longitudinally spaced apart latching features for cooperation with the latching mechanism to latch the slide in one of at least two longitudinal positions; and
a buckle connected to the buckle end of the longitudinal slide and receiving the belts
wherein the latching mechanism forms a guide;
the longitudinal slide slides longitudinally through the guide;
wherein the latching mechanism further comprises:
a housing;
a pin extending through the housing and having an engaging end aligned to engage the latching features and a knob end opposite the engaging end;
a spring residing in the housing and biasing the pin in an inward direction to engage one of the latching features; and
a knob attached to the knob end of the pin, the knob biased toward the housing by the spring.
2. The buckle adjuster of claim 1 , wherein the housing is an open housing.
3. The buckle adjuster of claim 2 , wherein:
the housing includes a top plate and a base plate;
the spring resides between the base plate and the top plate; and
the pin extends through the base plate to engage the latching features.
4. The restraint system of claim 3 , wherein:
the latching mechanism resides above a top surface of the longitudinal slide;
a connecting plate resides opposite the latching mechanism below a bottom surface of the longitudinal slide;
spacers reside between the latching mechanism and the connecting plate defining the guide; and
the connecting plate connects the latching mechanism to the latch end of the arm.
5. The restraint system of claim 4 , wherein:
the connecting plate includes a pin passage; and
in a latched position, the pin passes through the base plate, through the longitudinal slide and at least partially through the connecting plate.
6. A restraint system comprising:
a shoulder inertial reel;
a shoulder belt extendable from the shoulder inertial reel and having a shoulder belt connector;
a lap inertial reel;
a lap belt extendable from the lap inertial reel and having a lap belt connector;
a buckle mount connected to a vehicle;
a buckle adjuster connected to the buckle mount, the buckle adjuster comprising:
an arm having a mount end and a latch end, the mount end attached to the mount;
a connecting plate attached to the latch end of the arm;
a latching mechanism attached to the connecting plate and including a pin biased toward the connecting plate;
a guide formed between the connecting plate and the latching mechanism; and
a longitudinal slide having a stop end and a buckle end and at least two longitudinally spaced apart latching features for cooperation with the pin to latch the longitudinal slide in one of at least two longitudinal positions; and
a buckle attached to the buckle end of the longitudinal slide.
