Abstract

Abstract An anthropomorphic test dummy torso is provided with a spine mechanism extending from the pelvis upwardly to the chest. The spine mechanism comprises a plurality of vertically stacked pivot means mounted on a support platform located at the pelvis. The pivot means provide a pivot axis located at the waist line about which the torso is bendable in fore and aft directions, a vertical spinal axis about which the torso is twistable above its waist line, and an axis normal to the vertical spinal axis about which the torso is bendable sideways. An elastomeric isolation means above the stacked pivot means provides pelvis-to-chest shock and vibration isolation.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 171 words
An anthropomorphic test dummy torso having a spine mechanism extending from the pelvis upwardly to the chest, the spine mechanism comprising a plurality of pivot means vertically stacked one above the other, the stacked pivot means being mounted on a support platform at the pelvis, a first one of the pivot means providing a first pivot axis located relative to the pelvis on a line corresponding generally to a torso waist line about which the torso is bendable in fore and aft directions, the first one of the pivot means includes viscous damping means to inhibit fore and aft whiplash movement of the torso about the waist line pivot axis, a second one of the pivot means providing a vertical spinal axis about which the torso is twistable above its waist line, and a third one of the pivot means providing an axis normal to the vertical spinal axis about which the torso is bendable sideways, and elastomeric isolation means above the stacked pivot means providing pelvis-to-chest shock and vibration isolation.
Claim 2
Dependent Claim 171 words
An anthropomorphic test dummy torso having a spine mechanism extending from the pelvis upwardly to the chest, the spine mechanism comprising a plurality of pivot means vertically stacked one above the other, the stacked pivot means being mounted on a support platform at the pelvis, a first one of the pivot means providing a first pivot axis located relative to the pelvis on a line corresponding generally to a torso waist line about which the torso is bendable in fore and aft directions, the first one of the pivot means includes viscous damping means to inhibit fore and aft whiplash movement of the torso about the waist line pivot axis, a second one of the pivot means providing a vertical spinal axis about which the torso is twistable above its waist line, and a third one of the pivot means providing an axis normal to the vertical spinal axis about which the torso is bendable sideways, and elastomeric isolation means above the stacked pivot means providing pelvis-to-chest shock and vibration isolation.
Claim 3
Dependent Claim 104 words
An anthropomorphic test dummy torso accordIng to claim 1, in which: the viscous damping means comprises a housing having a fluid filled chamber, the housing being pivotally supported on the support platform for swinging movement about the first pivot axis, a braking member within the chamber immovable relative to the support platform, and orifice means in the braking member metering flow of fluid from one side of the braking member to the other side as the housing swings about the first pivot axis as the torso undergoes fore and aft movement, the second and third pivot means being stacked on top of the housing.
Claim 4
Dependent Claim 55 words
An anthropomorphic test dummy torso according to claim 1, in which: the first one of the pivot means comprises a pivot shaft fixedly supported on the support platform, and a housing for a viscous fluid used in the viscous damping means, the housing being swingable in a fore and aft direction about the pivot shaft.
Claim 5
Dependent Claim 44 words
An anthropomorphic test dummy torso according to claim 3, in which: the second pivot means is supported on the housing, and the third pivot means comprises pivot studs journalled on the second pivot means and a support plate frictionally coupled to the pivot studs.
Claim 6
Dependent Claim 35 words
An anthropomorphic test dummy torso according to claim 4, in which: the elastomeric isolation means is interposed between the support plate and a connecting member for connecting the spine mechanism to the dummy torso chest.
