Abstract
Abstract A distribution device in the passenger space of a motor vehicle for the air arriving from an inlet opening of a chamber towards two ducts extending from said chamber and reaching air outlet nozzles, usually upper and lower, which comprises a flap rotatably mounted, for the distribution, about an axis at a distance from the air inlet opening. The flap has two branches forming a V with an obtuse apex angle and controlling the respective inlets of the ducts and the edges of which, which are remote for the pivoting axis, are constantly in the respective outlet ducts.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
142 words
A device for distributing in a passenger space of a motor vehicle the air arriving from at least one channel into an inlet opening for two ducts, comprising a flap with two branches forming a V rotatably mounted on an axis, a first branch of the flap being able to control the opening and shutting off of the first duct, a second branch of the flap being able to control the opening and shutting off of the second duct, wherein a second flap is mounted on the edge of one of the branches of the V-shaped flap which is remote from the pivoting axis, means being provided for independently displacing said second flap when said one branch is in the shutting off position of the duct which it controls so as to control the opening and shutting off of the inlet opening.
Claim 2
Independent Claim
142 words
A device for distributing in a passenger space of a motor vehicle the air arriving from at least one channel into an inlet opening for two ducts, comprising a flap with two branches forming a V rotatably mounted on an axis, a first branch of the flap being able to control the opening and shutting off of the first duct, a second branch of the flap being able to control the opening and shutting off of the second duct, wherein a second flap is mounted on the edge of one of the branches of the V-shaped flap which is remote from the pivoting axis, means being provided for independently displacing said second flap when said one branch is in the shutting off position of the duct which it controls so as to control the opening and shutting off of the inlet opening.
Claim 3
Dependent Claim
25 words
The device according to claim 1, wherein the second flap is rotatably mounted about the edge of said branch which is remote from the axis.
Claim 4
Dependent Claim
39 words
The device according to claim 1 or 2, wherein there is a kinematic connection between the second flap and said branch so that the same driving member provides control of the V-shaped flap and control of the second flap.
Claim 5
Dependent Claim
54 words
The device according to claim 3, wherein the control of the second flap applies first one of the edges of said second flap with a pressure against a first cooperating ridge of the inlet opening, and then the opposite edge against another cooperating ridge of said inlet opening, thereby shutting off said inlet opening.
Claim 6
Dependent Claim
47 words
The device according to claim 1 or 2, wherein the axis about which is rotatably mounted the first flap forms a portion of a bent rod having a second portion which is parallel thereto and connected to the second flap through a stirrup mounted on the latter.
Claim 7
Dependent Claim
48 words
The device according to claim 5, wherein in the vicinity of the edge of said one branch of the first flap on which is mounted the second flap, said branch is deflected so that the second flap provided with its stirrup may be disposed parallel to said branch.
Claim 8
Dependent Claim
29 words
The device according to claim 1, wherein the second flap carries on its side edges pins provided for guiding it in slides of the side walls of the device.
Claim 9
Dependent Claim
88 words
The device according to claim 7, wherein each of said slides comprises a first portion of slide which is defined by segments of circles the center of which corresponds to the edge of said one branch of said first flap when the latter is in the shutting off position of the duct which it controls, said first portion of slide being connected to a second portion of slide which is defined by segments of circles the center of which corresponds to the mounting axis of said first flap.
Claim 10
Dependent Claim
23 words
The device according to claim 1, wherein the second flap carries a joint provided for the tight shutting off of the inlet opening.
Claim 11
Dependent Claim
97 words
The device according to claim 1, wherein there is upstream of the inlet opening, in the vicinity of the latter, a heat exchanger and means for directing towards the exchanger an adjustable porportion of the admitted outer air, the air directed towards the exchanger flowing directly towards the distribution device, said device being such that for the various positions of the V-shaped flap, the portion common to the two ducts which is adjacent the inlet opening in the device has a volume sufficient for an appropriate mixing of the hot air and the cold air flowing therethrough.
Claim 12
Dependent Claim
35 words
The device according to claim 1, wherein the branch of the V-shaped flap on which is not mounted the second flap carries a joint for providing a tight closing of the duct which it controls.
