Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
119 words
A device for mounting a motor-blower unit at the air inlet of a heating or air-conditioning installation of the passenger space of a motor vehicle, said motor-blower unit having a motor cage and said device comprising a cylindrical cradle for receiving and supporting the motor cage and which is provided with abutments for cooperating with a lower edge of the cage, wherein the cradle comprises hooking means formed by longitudinal fingers with resilient attachment, opening out when the motor cage is driven into the cradle and bearing against the cage at the end of the driving-in movement, said fingers ending into hooks which come in engagement with an upper edge of the cage for fixing the latter against movement.
Claim 2
Independent Claim
119 words
A device for mounting a motor-blower unit at the air inlet of a heating or air-conditioning installation of the passenger space of a motor vehicle, said motor-blower unit having a motor cage and said device comprising a cylindrical cradle for receiving and supporting the motor cage and which is provided with abutments for cooperating with a lower edge of the cage, wherein the cradle comprises hooking means formed by longitudinal fingers with resilient attachment, opening out when the motor cage is driven into the cradle and bearing against the cage at the end of the driving-in movement, said fingers ending into hooks which come in engagement with an upper edge of the cage for fixing the latter against movement.
Claim 3
Dependent Claim
19 words
A device according to claim 1, wherein the cradle comprises axial and angular guiding means of the motor cage.
Claim 4
Dependent Claim
32 words
A device according to claim 1, wherein, the cradle being made of a plastics material, the resiliency of the fingers is provided by the narrowness of their attachment to the cradle body.
Claim 5
Dependent Claim
26 words
A device according to claim 3, wherein outer protrusions connected to the resilient fingers depend from the cradle for controlling the opening out of said fingers.
Claim 6
Dependent Claim
20 words
A device according to claim 4, wherein one outer protrusion and one resilient finger are shaped according to a square.
Claim 7
Dependent Claim
35 words
A device according to claim 5, wherein a branch of the square which is perpendicular to the finger is of clear access in spite of the presence of the motor-blower unit mounted into the device.
Claim 8
Dependent Claim
18 words
A device according to claim 3, wherein the upper ends of the fingers have a slightly excentered face.
Claim 9
Independent Claim
20 words
A device according to one of the preceding claims, wherein the cradle is formed by the assembly of two half-cradles.
Claim 10
Dependent Claim
18 words
A device according to claim 8, wherein the resilient fingers are adjacent the assembly edges of two half-cradles.
Claim 11
Dependent Claim
23 words
A device according to claim 8, which is further formed of two halves with a diametral junction, each of which comprises a half-cradle.
Claim 12
Dependent Claim
31 words
A device according to claim 10, wherein each half comprises a half-ferrule, the two half-ferrules bounding after the assembly the circulation sleeve where the air is circulated by the unit blower.
Claim 13
Dependent Claim
26 words
A device according to claim 8, wherein the two halves comprise means for their assembly by gripping or clipping when they are brought near each other.
Claim 14
Dependent Claim
35 words
A device according to claim 10, wherein one half is formed with an assembly hook resiliently mounted and the other with an opening for the engagement of the hook when being brought near each other.
Claim 15
Dependent Claim
21 words
A device according to claim 13, wherein an opening is provided on one branch operating the opening out of the finger.
Claim 16
Dependent Claim
39 words
A device according to claim 12, wherein the assembly means of the two halves are such that after their hooking in, there remains an intentional clearance, said clearance being cancelled when driving-in the electrical motor cage inside the cradle.
Claim 17
Dependent Claim
28 words
A device according to claim 15, wherein the hooking means, when the two halves are being assembled, are put under tension when the cage is completely driven in.
Claim 18
Dependent Claim
32 words
A device according to claim 1 or 2, wherein the cradle comprises means capable of cooperation with crimpings in relief formed on the cage for providing the angular positioning of the unit.
Claim 19
Dependent Claim
28 words
A device according to claim 17, wherein conductive resilient clamps depending from the cradle are capable of receiving unit conductive tongues for the electrical supply of the motor.
