Abstract: An air treatment system for an agricultural vehicle includes an air filtration apparatus having an air filter housing for receiving an air filter cartridge and downstream air processing apparatus fluidly connected with the air filter housing by a duct. The system can receive first and second type air filter cartridges having corresponding first and second outlet sealing configurations. The duct has inner and outer conduits that define an inner flow path and an outer flow path. A filter sealing arrangement of the duct can engage with either type of filter cartridge. This enables two different types of filter cartridge, which may be configured to provide different levels of filtration, to be selectively mounted to the system in the same housing. Air flow may be restricted to the inner flow path when one type of air filter cartridge is fitted.

Abstract: An air filtration system for an operator environment of an agricultural vehicle including at least one external inlet, a first filtration device having a coarser level of filtration located between the external inlet and an HVAC system, a second filtration device having a second finer level of filtration and an associated blower located between the external inlet and the HVAC system where the air filtration system selectively connects either the first filtration device to the HVAC system blower or the second filtration device and its associated blower to the HVAC system blower and a bypass permanently connects the HVAC system blower and the second filtration device.

Abstract: Vehicle cab windscreen air distribution system for a windscreen (1) provided with an external windscreen wiper (5) and a windscreen wiper motor (2a) mounted on the inside of the windscreen. The distribution system comprises an air distribution housing (3) which at least partially surrounds the wiper motor (2, 2a), the housing defining a passage (3a) for the supply of air onto the windscreen (1a) in the vicinity of the motor.

Abstract: A tractor cab HVAC system has a blower (22) which draws air into the system via air intake means (13) in the roof (14) of the cab (10). Ducting (15) in the roof of the cab directs air drawn in via the intake means down the center of one or more hollow adjacent pillars (16) of the cab to an air filter (18) contained in a housing (20) located between the adjacent pillars. Further ducting (19) extends from the air filter housing to an HVAC unit (11), the HVAC unit processing the air drawn into the system prior to discharging the processed air into the cab. The filter housing (20) is of generally rectangular form and is connected at opposite ends to the two hollow adjacent pillars (16) of the cab via inlet openings (20a) in the housing to allow the passage of intake air from the pillars to the filter (18).

Abstract: A generally rectangular tractor cab air filter housing arrangement (20) has a main body portion with inlet zones (20a) at each end through which air enters the housing, a first outlet aperture (20c) in the housing over which a filter element (18) is supported, and a second aperture in the housing in which a door (21) is pivoted to provide access to the filter for maintenance. The inlet zones (20a) are formed as chambers which are structurally interconnected by side portions (20d) of the housing so that the housing can be formed as a single piece hollow plastics molding. The door (21) may also be a hollow single piece plastics molding. Both the housing and/or the door may be formed by blow molding or rotational molding.

Abstract: A tractor cab filter housing (20) has at least one air intake (20a) through which air is drawn into the housing, an outlet (20c) through which air leaves the housing, a filter element (18) positioned between the inlet and outlet, and an opening access door (21) through which the filter element can be accessed for servicing/replacement. The housing access door (21) includes an integral storage chamber (21f) in which liquids or other items can be stored. The housing door is a hollow plastics molding having an access opening (21d) through which liquid can be introduced into the storage chamber, the opening having a cap (21e) for closing of the opening. A pump (50) may be provided for pumping the liquid out of the storage chamber.

Abstract: An apparatus and method for folding and packaging an airbag includes a tapered concentrator. The airbag can be a head or side-window airbag. The concentrator has an inlet and an outlet whose dimension is smaller than the inlet. Feeding the airbag through the concentrator squeezes or compresses (i.e., folds) the airbag to a predetermined cross section corresponding the outlet size of the concentrator. The airbag can include a strap at one end portion thereof. The strap is feed through the concentrator, such as by pulling the strap therethrough. Pulling the strap pulls the airbag through the smaller outlet, which compresses or folds the airbag. Also, by placing an airbag package having an inlet sized to the outlet of the concentrator adjacent to the outlet of the concentrator, and feeding the strap through the airbag package, the folded airbag is inserted into the package substantially simultaneously with the folding operation. The concentrator can include pre-orienting elements for forming uniform folds.
