Abstract

An apparatus for inducing seat belt usage by the driver of a vehicle, said apparatus comprising:

a seat belt, said seat belt carrying a seat belt buckle, a latching clasp for releasable engagement of said buckle and a presence detector for acknowledging when said buckle is engaged in said latching clasp.

Claims

1. An apparatus for inducing seatbelt usage by a driver of a vehicle including an engine, said apparatus comprising:

a seat belt, said seat belt carrying a seat belt buckle;

a latching clasp for releasable engagement of said seat belt buckle;

a presence detector for acknowledging when said seat belt buckle is engaged in said latching clasp; and

a vehicle control unit for controlling engine output power and speed of the vehicle,

wherein said vehicle control unit is arranged to operate said vehicle in a first mode, if the presence detector has indicated that said seat belt buckle is engaged in said latching clasp,

and in a second mode if the presence detector has indicated that said seat belt buckle is not engaged in said latching clasp,

wherein in the first mode the speed of the vehicle is higher than an idle speed, and,

wherein maximum speed of the second mode is more than 75% of maximum speed of the first mode.

2. An apparatus according to claim 1 wherein the maximum speed of the second mode is more than 90% of the maximum speed of the first mode.

3. An apparatus for inducing seatbelt usage by a driver of a vehicle including an engine, said apparatus comprising:

a seat belt, said seat belt carrying a seat belt buckle;

a latching clasp for releasable engagement of said seat belt buckle;

a presence detector for acknowledging when said seat belt buckle is engaged in said latching clasp; and

a vehicle control unit for controlling engine output power and speed of the vehicle,

wherein said vehicle control unit is arranged to operate said vehicle in a first mode, if the presence detector has indicated that said seat belt buckle is engaged in said latching clasp,

and in a second mode if the presence detector has indicated that said seat belt buckle is not engaged in said latching clasp,

wherein in the first mode, the speed of the vehicle is higher than an idle speed, and,

wherein a difference between maximum speeds of the first and second modes is less than 20 mph.

4. An apparatus according to claim 3 wherein the difference between the maximum speeds of the first and second modes is less than 5 mph.

5. An apparatus for inducing seatbelt usage by a driver of a vehicle including an engine, said apparatus comprising:

a seat belt, said seat belt carrying a seat belt buckle;

a latching clasp for releasable engagement of said seat belt buckle;

a presence detector for acknowledging when said seat belt buckle is engaged in said latching clasp; and

a vehicle control unit for controlling engine output power and speed of the vehicle,

wherein said vehicle control unit is arranged to operate said vehicle in a first mode, if the presence detector has indicated that said seat belt buckle is engaged in said latching clasp,

and in a second mode if the presence detector has indicated that said seat belt buckle is not engaged in said latching clasp,

wherein in the first mode, the speed of the vehicle is higher than an idle speed, and,

wherein maximum engine power output of the second mode is more than 75% of maximum engine power output of the first mode.

6. An apparatus according to claim 5 wherein maximum engine power output of the second mode is more than 90% of maximum engine power output of the first mode.

7. A method for inducing seat belt usage by a driver of a vehicle, said method including the steps of:

detecting the presence of a seat belt buckle in a latching clasp for releasable engagement of said seat belt by a presence detector for acknowledging when said seat belt buckle is engaged in said latching clasp;

transmitting a signal from said presence detector to a vehicle control unit for controlling-engine output power and speed of the vehicle; and

arranging said vehicle control unit to operate said vehicle in a first mode if the presence detector has indicated that said seat belt buckle is engaged in said latching clasp,

and in a second mode if the presence detector has indicated that said seat belt buckle is not engaged in said latching clasp,

wherein in the first mode, the speed of the vehicle is higher than an idle speed, and

wherein maximum speed of the second mode is more than 75% of maximum speed of the first mode.

8. A method according to claim 7 wherein the maximum speed of the second mode is more than 90% of the maximum speed of the first mode.

9. A method for inducing seat belt usage by a driver of a vehicle, said method including the steps of:

detecting the presence of a seat belt buckle in a latching clasp for releasable engagement of said seat belt by a presence detector for acknowledging when said seat belt buckle is engaged in said latching clasp;

transmitting a signal from said presence detector to a vehicle control unit for controlling engine output power and speed of the vehicle; and

arranging said vehicle control unit to operate said vehicle in a first mode if the presence detector has indicated that said seat belt buckle is engaged in said latching clasp,

and in a second mode if the presence detector has indicated that said seat belt buckle is not engaged in said latching clasp,

wherein in the first mode, the speed of the vehicle is higher than an idle speed, and,

wherein a difference between maximum speeds of the first and second modes is less than 20 mph.

10. A method according to claim 9 wherein the difference between the maximum speeds of the first and second modes is less than 5 mph.

11. A method for inducing seat belt usage by a driver of a vehicle, said method including the steps of:

detecting the presence of a seat belt buckle in a latching clasp for releasable engagement of said seat belt by a presence detector for acknowledging when said seat belt buckle is engaged in said latching clasp;

transmitting a signal from said presence detector to a vehicle control unit for controlling engine output power and speed of the vehicle; and

arranging said vehicle control unit to operate said vehicle in a first mode if the presence detector has indicated that said seat belt buckle is engaged in said latching clasp,

and in a second mode if the presence detector has indicated that said seat belt buckle is not engaged in said latching clasp,

wherein in the first mode, the speed of the vehicle is higher than an idle speed, and,

wherein maximum engine power output of the second mode is more than 75% of maximum engine power output of the first mode.

12. A method according to claim 11 wherein maximum engine power output of the second mode is more than 90% of maximum engine power output of the first mode.
