Air-conditioning system of motor vehicle

Claim 2

An air-conditioning system for use in a motor vehicle having a vehicle body including a floor panel, a roof panel, and a side wall member and a seat structure mounted on the floor panel and located inside and adjacent said side wall member, the air-conditioning system comprising an air-conditioner assembly which is positioned between said seat structure and said side wall member and which includes at least one heat exchanger unit and a covering member having the heat exchanger unit enclosed in a space which is defined by the covering member, said floor panel and said side wall member and which is located above the floor panel, said covering member having a substantially horizontal upper panel portion located sidewise inwardly of said side wall member and outwardly of said seat structure and above a horizontal plane flush with the upper surface of the cushion portion of said seat structure so that the covering member is operable as an armrest for an occupant of said seat structure.

Claim 3

An air-conditioning system as set forth in claim 1, further comprising a duct structure comprising a pair of tubular side segments and a tubular intermediate segment, each of said side segments extending vertically along the inner surface of said side wall member, said intermediate segment longitudinally extending between said side segments along and in proximity to the lower surface of said roof panel generally in a transverse direction of the vehicle body and having opposite longitudinal end portions respectively connected to the side segments, one of said side segments extending in part upwardly from said covering member and communicating with said heat exchanger.

Claim 4

An air-conditioning system as set forth in claim 1 or 2, in which said vehicle body further includes a pair of wheel housings aligned with each other in a lateral direction of the vehicle body, one of the wheel housings being located substantially sidewise of the seat structure, said air-conditioner assembly being positioned above said one of the wheel housings.

Claim 5

An air-conditioning system as set forth in claim 2, in which said covering member is externally coated with a pad.

Claim 6

An air-conditioning system as set forth in claim 4, in which said pad has an external surface colored substantially similarly to the external surfaces of said seat structure.

Claim 7

An air-conditioning system as set forth in claim 2, in which each of said side segments and said intermediate segment is constructed of a laminar panel structure composed of an inner layer of a rigid synthetic resin, an intermediate layer of a heat insulating material securely attached to the outer surface of the inner layer, and an outer layer of a decorative web.

Claim 8

An air-conditioning system as set forth in claim 6, in which said heat insulating material is polyurethane.

Claim 9

An air-conditioning system as set forth in claim 6, in which said decorative web is a leather.

Claim 10

An air-conditioning system for use in a motor vehicle having a vehicle body including a floor panel, a roof panel, and a side wall member and a seat structure mounted on the floor panel and located inside and adjacent said side wall member, the air-conditioning system comprising an air-conditioner assembly which is positioned between said seat structure and said side wall member and which includes at least one heat exchanger unit and a covering member having the heat exchanger unit enclosed in a space which is defined by the covering member, said floor panel and said side wall member and which is located above the floor panel, said covering member having a substantially horizontal upper panel portion located sidewise inwardly of said side wall member and outwardly of said seat structure and above a horizontal plane flush with the upper surface of the cushion portion of said seat structure so that the covering member is operable as an armrest for an occupant of said seat structure, and a duct structure comprising a pair of tubular side segments and a tubular intermediate segment, each of said side segments extending vertically along the inner surface of said side wall member, said intermediate segment longitudinally extending between said side segments along and in proximity to the lower surface of said roof panel generally in a transverse direction of the vehicle body and having opposite longitudinal end portions respectively connected to the side segments, one of said side segments extending in part upwardly from said covering member and communicating with said heat exchanger, wherein each of said side segments has an upper end portion located immediately underneath the lower surface of said roof panel and overlapped by each of said longitudinal end portions of said intermediate segments.

Claim 11

An air-conditioning system for use in a motor vehicle having a vehicle body including a floor panel, a roof panel, and a side wall member and a seat structure mounted on the floor panel and located inside and adjacent said side wall member, the air-conditioning system comprising an air-conditioner assembly which is positioned between said seat structure and said side wall member and which includes at least one heat exchanger unit and a covering member having the heat exchanger unit enclosed in a space which is defined by the covering member, said floor panel and said side wall member and which is located above the floor panel, said covering member having a substantially horizontal upper panel portion located sidewise inwardly of said side wall member and outwardly of said seat structure and above a horizontal plane flush with the upper surface of the cushion portion of said seat structure so that the covering member is operable as an armrest for an occupant of said seat structure, and a duct structure comprising a pair of tubular side segments and a tubular intermediate segment, each of said side segments extending vertically along the inner surface of said side wall member, said intermediate segment longitudinally extending between said side segments along and in proximity to the lower surface of said roof panel generally in a transverse direction of the vehicle body and having opposite longitudinal end portions respectively connected to the side segments, one of said side segments extending in part upwardly from said covering member and communicating with said heat exchanger, wherein each of said side segments has an upper end portion located immediately underneath the lower surface of said roof panel and overlapped by each of said longitudinal end portions of said intermediate segments.

Claim 12

An air-conditioning system as set forth in claim 9, in which one of said intermediate segment and each of said side segments is formed with at least one slot elongated in a lateral direction of the vehicle body, the upper end portion of each of said side segments and each of the longitudinal end portions of said intermediate segment being connected together by means of at least one connecting element fastened thereto through said slot.
