Abstract: A display panel mounting assembly includes a dome-shaped lower bearing member on a support member, an upper bearing member, and a carrier member attached to the display panel and held between the upper and lower bearing members. The lower bearing member has a central bore and a pair of stops projecting from opposite sides of the bore. The carrier member has a opening which receives the stops. A stop post projects from the support member adjacent the bearing member. An aperture which receives the post is formed in the carrier spaced apart from the opening. The opening and the tabs cooperating to control pivoting of the carrier member with respect to the support member in one degree of freedom. The aperture and the post cooperate to control pivoting of the carrier member in a second degree of freedom.

Abstract: An armrest assembly includes an armrest base unit. The base unit has a side portion forming a channel member. First and second auxiliary units may be mounted to the base unit. Each auxiliary unit has an attachment member which is received by and mates with the channel member. A slot and bores are formed in a bottom surface of the channel member. Screws extend through the slot and bores and are screwed into the auxiliary units. The attachment and channel members have mating U-shaped cross-sectional shapes.

Abstract: A one piece rotational molded roof for a vehicle cab is provided in which separate inlet and outlet air ducts are molded in the roof. The ducts are formed by molding upper and lower panels that are widely spaced to form the ducts and which are closely spaced about the periphery of the ducts. After a solid surface layer is molded, a second resin charge containing a foaming agent is dropped in the mold. This resin coats interior of the solid surface layer and later foams. The foam expands and extends completely between the closely spaced upper and lower panels of the solid surface layer to seal between the inlet and outlet air ducts. The foam is rigid to strengthen the roof.
