hello everyone!

does this sentence sound right when translated to french?

English :
" Concept Seating was established in 1991 after a police officer, who suffered back problems, designed and produced rough sketches of a new innovative seat that would help relieve back pain."

French:
" Établi en 1991 lorsqu’un policier qui a souffert des problèmes de dos a conçu un croquis d’un nouveau siège innovateur qui pouvait réduire les douleurs dorsales."

Many thanks!

 

Some possible tweaking...

 

Thank you, the tweaking looks good!
