What is claimed is: 1. An airbag apparatus for protecting an occupant in a vehicle, comprising: an airbag having a plurality of divided chambers therein; a gas generator attached to the airbag for inflating the same; and a gas distributor attached to the gas generator for directly supplying gas to each of the plurality of the chambers, said gas distributor covering only a lower part of the gas generator and having one gas outlet at a bottom thereof oriented downwardly to eject the gas downwardly and another gas outlet at a side thereof oriented laterally to eject the gas laterally so that said gas generator supplies the gas to each of the plurality of the chambers through each of the gas outlets of the gas distributor. 2. An airbag apparatus according to claim 1, wherein said gas outlets of the gas distributor have dimensions adjusted according to inflation characteristics of each of the plurality of the chambers. 3. An airbag apparatus according to claim 1, wherein said gas outlets of the gas distributor have different dimensions so that each of the plurality of the chambers has a predetermined internal pressure when the airbag is inflated. 4. An airbag apparatus according to claim 3, wherein said airbag has a partition panel extending substantially horizontally therein to substantially completely divide the airbag into two chambers when the airbag is inflated, each of said gas outlets being connected to the divided chambers. 5. An airbag apparatus according to claim 4, wherein said gas generator is located inside the airbag. 6. An airbag apparatus according to claim 1, wherein said one and another gas outlets have portions branching outwardly from a portion covering the gas generator. 7. An airbag apparatus according to claim 1, wherein said gas outlets are located at least inside the divided chambers. 8. An airbag apparatus according to claim 1, wherein said gas distributor has a cylindrical shape covering only the lower part of the gas generator. 9. An airbag apparatus according to claim 8, wherein said gas distributor is made of cloth. 10. An airbag apparatus according to claim 8, wherein said airbag has a partition panel extending substantially horizontally therein to substantially completely divide the airbag into upper and lower chambers when the airbag is inflated, said gas generator being located inside the upper chamber. 11. An airbag apparatus according to claim 10, wherein said one gas outlet projects from the gas distributor and is located in the lower chamber, and said another gas outlet ejects gas in the upper chamber.
