The EuroCopter Tiger ejection seats are designed to blow out sideways and down to stay away from the prop. The two Russian choppers that eject do the same but they blow the prop away at the same time the seats go sideways. In a fighter aircraft, they are designed to go up. Not sure if I, or many pilots, would want to use it. Depending upon how much control they have of the aircraft will determine if the ground is coming up at them or they will be firing the egress sideways at it.

I’m not sure about the Tiger, but the Russian Kamovs with ejector seats blow the rotor disc off and then the canopy, then fire the fighter style ejection seats.
https://en.wikipedia.org/wiki/Kamov_Ka-50
“For improved pilot survivability the Ka-50 is fitted with a NPP Zvezda (transl. Star) K-37-800 ejection seat, which is a rare feature for a helicopter.[21] Before the rocket in the ejection seat deploys, the rotor blades are blown away by explosive charges in the rotor disc and the canopy is jettisoned.[22]”

The Mi-28 is the Russian chopper that drops the hapless crewman to the side and down. It’s not a true ejection seat, more like a bail-out chute where it dumps the seat and occupant out. You have to have significant altitude to use it safely while the Kamov system is a true zero-zero system.
Back in the US, the Sikorsky S-72 research and development mule had ejection seats that worked much like the Ka-50 and 52’s, so you can see how it works: https://www.youtube.com/watch?v=jLhZN7fTwQQ
