The extended cloud complex containing the supernova remnant IC 443, the H II region S 249 and members of the Gem OB 1 association is studied with IRAS observations at 12, 25, 60 and 100 microns and WSRT observations at 327 and 1400 MHz and in the 21 cm H I line. IC 443 is shown to consist of three interconnected approximately spherical subshells of vastly different radii and centroids. The geometry is fully constrained by the structural and kinematic data. Two of these subshells together define the usually assumed boundaries of IC 443, while the third includes the optical filaments which extend beyond the bright north-eastern rim. These filaments are shown to have well correlated nonthermal radio counterparts. Physical parameters are derived for the entire complex, individual H II regions and the shocked and recombined gas within IC 443 from the radio and infrared data. The available evidence implies that the SNR shock has encountered a pre-existing high density shell. It is shown that the system of subshells is fully consistent with formation by stellar wind driven bubbles generated by association members within the inhomogeneous environment of the complex.
