International Classification:

A47B 96/06

US Classification:

24822022, 248232, 165 41, 165 51, 165 67

Abstract:

A fastening system fastens a radiator, an electric fan support and a fan shroud as a single unit. The radiator has lower and upper posts to which slotted plates protruding from the fan support and fan shroud fit over. A structural sandwich is formed with the fan support lying between the radiator and the fan shroud. A flexible lever arm with a locking tab lies adjacent to the upper post of the radiator and connects to the radiator. When the fan support is fitted over the posts, the top plate of the electric fan support locks under the first lever arm tab. The fan shroud also has two slotted plates that also fit over the posts of the radiator. The fan shroud locks into place when a lever arm with a tab on the fan shroud locks under a tab that protrudes from the top plate of the fan support.

Assignee:

DENSO International America, Inc. - Southfield MI

International Classification:

F01D 25/24

US Classification:

4152141, 415220

Abstract:

A fan shroud assembly includes a fixed fan shroud and a removable fan shroud. An upper retention system integral with the fixed and removable fan shrouds secures the two circumferential ends of the removable fan shroud to the fixed fan shroud. A lower retention system integral with the fixed and removable fan shroud secures the center of the removable fan shroud to the fixed fan shroud. No additional fasteners are required to connect the removable fan shroud to the fixed fan shroud because of the integral nature of the upper and lower retention systems.

Christopher WISNIEWSKI - Ann Arbor MI, US

International Classification:

B60H 1/00

Abstract:

An HVAC system including a defrost manifold. The defrost manifold has a first side window outlet, a second side window outlet, and a windshield outlet. A first rib partially obstructs the first side window outlet. A second rib partially obstructs the second side window outlet. A control door is movable to open and close the defrost manifold. A first wall extends from a first portion of the control door that is opposite to the first side window outlet. A second wall extends from a second portion of the control door that is opposite to the second side window outlet. Movement of the control door varies the position of the first wall relative to the first rib, and varies the position of the second wall relative to the second rib, to control airflow through the first and second side window outlets

International Classification:

B60H 1/24
B60H 1/00

US Classification:

454152, 29464

Abstract:

Disclosed is a vehicle HVAC system that provides for installation, serviceability, or replacement of at least one actuator servo without removal of the HVAC assembly from the vehicle. As due to the tight space limitations, the present invention provides for at least one fastener-less mounting element of the servo assembly to be attached to the HVAC assembly, without the need for additional fasteners which would require additional space to access with a tool.
